SLOVAKIA   (Application no. 68066/12)                   JUDGMENT       STRASBOURG   26 July 2016   FINAL   28/11/2016   This judgment has become final under Article 44 § 2 of the Convention. It may be subject to editorial revision.   In the case of Adam v. Slovakia, The European Court of Human Rights (Third Section), sitting as a   Chamber composed of:   Luis López Guerra, President,   Helena Jäderblom,   Helen Keller,   Branko Lubarda,   Pere Pastor Vilanova,   Alena Poláčková,   Georgios A. Serghides, judges, and Stephen Phillips, Section Registrar, Having deliberated in private on 28 June 2016, Delivers the following judgment, which was adopted on that date: PROCEDURE 1.     The case originated in an application (no. 68066/12) against the Slovak Republic lodged with the Court under Article 34 of the Convention for the Protection of Human Rights and Fundamental Freedoms (“the Convention”) by a Slovak national, Mr Jaroslav Adam (“the applicant”), on 22 October 2012. 2.     The applicant was represented by Ms V. Durbáková, a lawyer practising in Košice. The Government of the Slovak Republic (“the Government”) were represented by their Agent, Ms M. Pirošíková. 3.     Relying on Articles 3 and 13 of the Convention, the applicant alleged, in particular, that he had been mistreated by the police during his detention, that there had not been an adequate investigation into his allegation, and that he had not had at his disposal an effective domestic remedy in that respect. 4.     On 2 April 2014 the application was communicated to the Government. THE FACTS I.     THE CIRCUMSTANCES OF THE CASE 5.     The applicant was born in 1994 and lives in Bidovce. He is of Romani origin. A.     Arrest and police custody 6.     At about 7 p.m. on 18 December 2010 a twelve-year old boy was mugged and his mobile phone taken from him while he was walking along a   road between two villages in south ‑ eastern Slovakia. The perpetrators of the mugging were not known to him. The boy and his parents subsequently reported the incident to the local county police. 7.     In response, a police unit consisting of three officers searched the area surrounding the crime scene with the boy and his father. At around 8 p.m. they spotted the applicant, who was then aged sixteen, another minor and a third person, all of whom the boy identified as his assailants. 8.     The applicant and his two associates, both of whom were also of Romani origin, were arrested. The parties dispute the circumstances of the arrest. The Government relied on entries in the county police logbook for the relevant night and on a note on the record drawn up by the county police dated 18 December 2010 indicating that the suspects had resisted arrest and attempted to flee. They had consequently had to   be subdued, no injuries had been sustained, and the use of force by the arresting officers had been found lawful. That material referred to the measures of restraint used against the applicant and the other two suspects as “self-defence mechanisms for holding and grabbing”. The applicant, for his part, denied that he had shown any resistance or that the police had used any measures of restraint. 9.     The applicant and his companions were then taken to the county police station. According to the results of a breathalyser test carried out there, all three detainees had consumed alcohol and the applicant was in a   state of slight inebriation. 10.     The three suspects were kept at the police station and preliminarily questioned ( vyťažení ) by officers from the county police. As to the rooms in which they were kept, these were used as offices, were fitted out with the usual office equipment and were not furnished as detention cells. 11.     The applicant’s and the Government’s accounts in relation to further details vary as follows. According to the applicant, during the probing, the officers subjected him to psychological pressure and physical violence with a view to obtaining his confession. In particular, he was slapped and punched in the head, was not allowed to sit or lie down or to rest during the entire length of his detention, and was not provided any food or drink. In the Government’s submission, there had been no ill-treatment, the three suspects were kept in separate rooms and were checked on at fifteen ‑ minute intervals. The applicant was allowed to use the toilet, which was equipped with a washbasin with drinkable tap water. 12.     The Public Prosecution Service (“the PPS”) was informed of the arrest and, at 11.10 p.m. the case file, along with the responsibility for the detention of the young men, was passed on to an investigator from the local district police. 13.     Meanwhile or in parallel, the victim was examined by a doctor, his mother orally submitted a criminal complaint, and the crime scene was inspected. B.     Charge 14.     In the early hours of 19 December 2010 the applicant and his two co-detainees were charged with robbery and the investigator decided to   place them in a facility for provisional detention. However, the decision was not implemented as no room was available in such a facility within a   reasonable distance. Subsequently, a legal-aid lawyer was appointed for the applicant and a   copy of the document containing the charges was sent to, inter alia , the child protection services. 15.     Between 12 noon and 1 p.m. on 19 December 2010 the applicant was brought before the investigator, who interviewed him in the presence of his mother and the lawyer. No mention was made of any ill ‑ treatment. 16.     At 1.50 p.m. the applicant was placed in a provisional detention cell as documented by a protocol, which cites him as submitting in response to a   pre-printed question that had not been subjected to any violence. The relevant documentation further contains a hand-written note with the applicant’s signature indicating that “[he] ha[d] received dinner”. According to the Government, the cell was equipped with, inter alia, a   washbasin and drinkable water from the tap. 17.     At 6.05 p.m. the applicant and his co-detainees were released, and the police took them home. 18.     When the applicant’s mother appeared before the investigator on 20   December 2010 she decided to avail herself of her right not to give evidence, making no mention of any ill-treatment. 19.     On 21 December 2010, acting through the intermediary of his lawyer, the applicant lodged an interlocutory appeal against the charge, arguing that he himself had not been involved in the mugging, which had been perpetrated by his minor associate alone and to which the latter had confessed. There was no mention of any ill-treatment. 20.     On 12 January 2010 the charge against the applicant was withdrawn. C.     Criminal complaint of ill-treatment in detention 21.     In the applicant’s submission, meanwhile, in the days that followed his release, his mother presented herself at the county police station and contacted the Ministry of the Interior by telephone to complain about the treatment to which her son had been subjected while detained. According to the applicant, her complaint was not registered and she was orally advised to submit it in written form. According to the Government, however, the heads of the county police and the district police, who were the only persons entitled to receive complaints in matters such as those obtaining in the present case, did not receive any complaint from the applicant’s mother. Similarly, there was no mention of a visit or any communication from her in the records of visits and telephone calls received by the county police or in the operational logbook of the district police. 22.     On 5 January 2011 the applicant and his associates lodged a written criminal complaint with the Ministry of the Interior. They directed it against the officers of the county police who had been on duty between 7 p.m. on 18 December 2010 and 10 a.m. on 19 December 2010, suggesting that the offence of abuse of authority of a public official could have been committed. In particular, they submitted that, while in police custody, each of them separately had been pressured to confess on the pretext that the others had already confessed. The applicant also submitted that he had been subjected to slapping in the face and on the head until he had confessed. The persons inflicting that treatment had worn uniforms. Although the applicant did not know their identity, he would certainly recognise them. Another person had been present, not wearing a uniform, presumably a   relative of the boy who had been robbed. Throughout the entire time in police custody, the applicant had had to   stand, without being allowed to sit or lie down, and he had not been given any food or water. Moreover, in the applicant’s submission, his legal guardians had not been notified of his custody, let alone been present. 23.     The applicant submitted a medical report dated 19 December 2010. The doctor who issued the report observed that the applicant had “allege[d] that he had been beaten by police officers the day before” and “had received a slap on the right half of a cheek”. In reply to a printed question about whether the injury could have been sustained as alleged, the reply “yes” was given. The doctor further observed that there was no haematoma and that the cheek was sensitive and slightly swollen. He diagnosed “a bruised cheek on the left” and classified the injury as slight, with recovery time below seven days. D.     Determination of the criminal complaint 24.     The criminal complaint was sent to the local Control and Inspection Section (“the CIS”) of the Ministry of the Interior for examination. Subsequently, the part of the complaint concerning the failure to notify the applicant’s legal guardians of his arrest and detention, to provide him with food and water during his detention, and to   hear him immediately after his arrest was sent to the district police (see paragraph 29 below). 25.     In examining the complaint concerning the alleged physical mistreatment, the CIS interviewed the applicant and his associates, as well as the investigator and two officers under suspicion. In addition, it examined the case file concerning the investigation into the alleged robbery and other documentary material. 26.     On 9 March 2011 the CIS dismissed the complaint. In doing so it observed that the applicant had not raised any complaint of ill-treatment during his interview with the investigator on 19 December 2010, and held that this could not be explained by his proclaimed fear of the officers involved since, in that interview, the applicant had been assisted by his mother and lawyer (see paragraph 15 above). The CIS observed that in his oral depositions, the applicant had claimed that he had been beaten at the county police station for about three hours and that he had sustained bruises and a swollen cheek. However, those allegations of sustained beating and its consequences did not correspond to the findings in the doctor’s report of 19   December 2010, which only attest to an allegation of having received a slap on the right cheek and to having a   swollen cheek, but no haematoma. The CIS also noted that in the investigation file concerning the alleged robbery there was no indication of any ill-treatment. It observed that the applicant’s injury could have been inflicted in the course of his arrest, which he had resisted and which accordingly had had to be carried out forcefully. In addition, the CIS observed that the police officers in question had not been involved in the investigation of the alleged robbery, but had merely been guarding the applicant. Consequently, they had had no reason to   pressure him into confessing. 27.     The applicant challenged the decision of 9 March 2011 by lodging an   interlocutory appeal with the PPS. He requested twice that a decision by the PPS to dismiss the appeal be reviewed. The applicant argued in particular that he had not resisted his arrest and that, accordingly, no physical force had been used in the course of it. His injury could therefore not be explained as the CIS had done. He had not complained of the ill-treatment before the investigator because nobody had asked him about it and because he had been concerned about possible repercussions. The applicant further argued that the fact that there was no mention of the ill-treatment in the investigation file was irrelevant. In fact, it was logical, because the officers involved would naturally not mention their misconduct and would deny it. That incongruity and contradiction of the arguments had not been examined. According to the applicant, a “racial motive was not excluded” and the treatment to which he had been subjected had been contrary to Article 3 of the Convention. 28.     The interlocutory appeal and the requests for review were eventually dismissed by the Office of the Prosecutor General (“the OPG”), which communicated its decision to the applicant in a letter of 29 September 2011. The PPS fully endorsed the findings of CIS, considering as crucial the fact that before the doctor on 19 December 2010 the applicant had only alleged slapping, that the doctor’s observations on the applicant’s injury did not correspond to the applicant’s subsequent allegation of sustained beating, and that the applicant had not raised any ill-treatment allegation with the investigator on 19 December 2010. Without any explanation, the PPS also concluded that there was no indication of any racial motive behind the treatment complained of by the applicant. 29.     As to the part of the applicant’s criminal complaint concerning the alleged failure to notify his legal guardians of his arrest and detention, to   provide him with food and water during his detention, and to   hear him immediately after his arrest (see paragraph 24 above), the district police informed the applicant in a letter of 8 June 2011, without any explanation at all, that “in the investigation of the given matter, no error had been committed by the investigative organs”. E.     Final domestic decision 30.     On 2 December 2011 the applicant lodged a complaint, under Article   127 of the Constitution, with the Constitutional Court against the OPG and the Regional Office of the PPS involved in his case. He emphasised that at the time of his arrest he had been a minor, that he had been kept at the police station the whole night without being able to   sit or lie down, and without being given any food or water, and that he had been subjected to psychological pressure and physical violence with a   view to forcing him to confess. He considered that such treatment had been in breach of his rights under Article 3 of the Convention, as was the ensuing investigation into his complaints on account of its lack of efficiency and independence, as well as the authorities’ failure to act on their own initiative. The applicant also alleged that the lack of a proper investigation had been aggravated by the lack of an effective remedy and discrimination, contrary to his rights under Articles 13 and 14 of the Convention. On the last point, the applicant argued that there had been many known incidents of police violence against the Roma in the course of arrest and detention in Slovakia, and that his treatment by the police had been influenced by his Romani origin. 31.     On 10 April 2012 the Constitutional Court rejected the complaint as manifestly ill-founded. It observed that the applicant had no legal right to   have a third person criminally prosecuted, that his right to lodge a   criminal complaint merely implied that he had the right “to have the complaint dealt with by a body authorised to   do so”, and that it had thus been dealt with. It further observed that the applicant had not complained of his alleged ill-treatment before the investigator on 19 December 2010 or in his interlocutory appeal against the charge (see paragraphs 15 and 19 above). The fact that he had had those means of asserting his rights at his disposal excluded the jurisdiction of the Constitutional Court. It concluded without further explanation that, in the circumstances, neither the proceedings before the PPS nor their decisions could have violated the applicant’s rights as identified in his constitutional complaint. The decision was served on the applicant on 25 April 2012. II.     INTERNATIONAL MATERIAL 32.     Various international material concerning the Situation of Roma in Slovakia at the relevant time has been summarised for example in the Court’s judgments in the cases of Mižigárová v. Slovakia (no. 74832/01, §§   57-63, 14 December 2010); V.C. v. Slovakia (no. 18968/07, §§ 78-84 and 146-49, 8 November 2011); and Koky and Others v. Slovakia (no. 13624/03, §   239, 12 June 2012). Further relevant material 1.     The European Commission against Racism and Intolerance (ECRI): Report (Fifth Monitoring Cycle) of 19 June 2014 on Slovakia (CRI[2014]37) 33.     The report contains the following passages: “... 3. Racist and homo/transphobic violence - Data 69.     Police ill-treatment (and generally speaking abusive behaviour) towards Roma have also been reported by the media, civil society and international organisations (IOs)... ... - Authorities’ response ... 77.     ... The most famous example with extensive media coverage concerns a group of Roma boys who were allegedly subjected to degrading treatment while detained by police officers in Košice in March 2009. Although the racist motivation of the crime was included in the indictment of 10 policemen in spring 2010 to date the case is still pending. More recently, in June 2013, NGOs and the media reported repressive police action in a village in the Kosice region, Moldava nad Bodvou, which allegedly resulted in injuries to over 30 individuals, including children. Only six months after the incident did the General Prosecutor’s office order an investigation into the police action which is still pending. ... 79.     ECRI reiterates its recommendation that... the Slovak authorities provide for a   body which is independent of the police and prosecution authorities, entrusted with the investigation of alleged cases of racial discrimination and misconduct by the police. 80.     ECRI also strongly reiterates its recommendation that the Slovak authorities ensure effective investigations into allegations of racial discrimination or misconduct by the police and ensure as necessary that the perpetrators of these types of acts are adequately punished. ...” 2.     European Committee for the Prevention of Torture and Inhuman or Degrading Treatment or Punishment: Report of 25 November 2014 on its visit to Slovakia in 2013 (CPT/Inf [2014] 29) 34.     The report contains, inter alia , the following: “11.     ... the [CPT] delegation did receive a number of consistent and credible allegations of physical ill ‑ treatment by police officers (including from several detained juveniles). Most of the allegations concerned the time period immediately after apprehension (even when the person concerned allegedly was not resisting apprehension or after he/she had been brought under control) and the period before and during police questioning. The alleged ill-treatment mostly consisted of slaps, punches and kicks to various parts of the body. In one case, the head of a detained juvenile was allegedly repeatedly banged against a wall by a police officer during questioning, apparently in an attempt to extract a confession. Another person met by the delegation stated that during his apprehension on the street, after having been brought under control by the police, he had been slapped in the face and kicked by a uniformed police officer... ... 16.     ...According to the information available, on 19 June 2013, some 60 police officers entered the settlement and individual houses, officially in an attempt to search for wanted individuals and stolen goods. [...] Following the operation, 15 persons were apprehended and escorted to the Moldava nad Bodvou sub-district police department where they spent several hours. Allegedly, in the course of the actual apprehension and subsequent detention, several individuals were ill-treated by the police.... 17.     In its report on the 2009 visit, the CPT referred to the incident of 21 March 2009, concerning the case of six Roma juveniles who had allegedly been forced, under threat of physical assault by police officers, to strip naked in a police station in Košice and to slap each other. Furthermore, they had allegedly been subjected to intimidation by police dogs. The Committee is concerned to note that, according to the information provided by the Slovak authorities during the 2013 visit, i.e. four-and ‑ a-half years after the alleged incident, the criminal case was still pending before the first instance court.... ...” 3.     UN Committee against Torture (CAT): Concluding Observations on the Third Periodic Report of Slovakia (2007-2013) of 8 September 2015 (CAT/C/SVK/CO/3) 35.     In paragraph 11 of its report, the Committee expressed its concern: “... (d) That no charges were brought against police officers who participated in the raid on 19 June 2013 on the Roma settlement of Moldava nad Bodvou in eastern Slovakia, which resulted in the apprehension of 15 persons, a number of whom reportedly were seriously ill-treated by the police during their apprehension and subsequent detention; (e) That all 10 policemen who physically abused and inflicted degrading treatment on six Roma juveniles in the city of Košice on 21 March 2009 were acquitted in the first instance judgement by the Košice II District Court on 27 February 2015, since the court refused to admit the video recording of the incriminating act as a legally obtained piece of evidence. ...” THE LAW I.     ALLEGED VIOLATION OF ARTICLES 3 AND 13 OF THE CONVENTION 36.     The applicant complained that he had been subjected to treatment prohibited under Article 3 of the Convention and that his allegations to that effect had not been properly investigated, contrary to the requirements of that provision and Article 13 of the Convention. Article 3 of the Convention reads as follows: “No one shall be subjected to torture or to inhuman or degrading treatment or punishment.” Article 13 provides that: “Everyone whose rights and freedoms as set forth in [the] Convention are violated shall have an effective remedy before a national authority notwithstanding that the violation has been committed by persons acting in an official capacity.” A.     Admissibility 37.     As to the Article 3 complaints, the Government objected that the applicant had failed to meet the requirement of exhaustion of domestic remedies under Article 35 § 1 of the Convention, in that he had not properly pursued his assertions at the domestic level and had failed to claim damages from the State under the Police Corps Act and the State Liability Act in relation to the treatment suffered at hands of State agents. Consequently, they considered the Article 13 complaint manifestly ill-founded. 38.     The applicant disagreed. 39.     The Court considers that, on the specific facts of the present case, the Government’s non-exhaustion objection in relation to the applicant’s Article   3 complaints raises issues which are closely related to the merits of these complaints and the complaint under Article 13 of the Convention. 40.     Accordingly, the Court finds that the complaints under Articles 3 and 13 of the Convention should be examined together and that the Government’s objection of non-exhaustion of domestic remedies should be joined to the merits of the Article 3 complaints. 41.     Other than that, the Court notes that the relevant part of the application is not manifestly ill-founded within the meaning of Article   35 §   3   (a) of the Convention. It further notes that it is not inadmissible on any other grounds. It must therefore be declared admissible. B.     Merits 1.     Substantive limb of Article 3 of the Convention (a)     Parties’ arguments 42.     The applicant alleged that he had been beaten, denied food and water, subjected to psychological pressure and racially discriminated against during his detention on 18 and 19 December 2010. 43.     The Government contested the applicant’s allegations as to the extent of his injury, the conditions of his detention and the treatment to which he had been subjected while detained. In particular, they pointed out that, on the evidence available, the applicant had only had a swollen and bruised left cheek, which he had attributed to a slap in the face (see paragraph 23 above), which was in contradiction of his allegations at the domestic level (see, for example, paragraph 26 above). In the Government’s submission, the applicant’s injury was caused by the measures used to overcome his resistance during his arrest, which measures had been lawful and legitimate. Moreover, the Government considered it incongruous on the one hand, that the applicant would have been beaten with a   view to pressing him into confessing, as he alleged, and on the other hand, that having not confessed, his version would have been promptly accepted by the investigator. The Government also contended that the officers at the county police station would not have had any reason to pressure him into confessing since shortly after his arrest it had become clear that the case fell outside the jurisdiction of the police and within the jurisdiction of the investigating authorities. Therefore, the police officers had merely held the applicant in custody and had played no role in the investigation of the case. In addition, the Government submitted that, contrary to his allegations, the applicant had been served dinner on 19 December 2010, although it was not possible to establish whether he had been served any breakfast and lunch on that day. In their submission, he had had access to drinking water on both 18 and 19 December 2010 (see paragraphs 11 and 16 above). The Government acknowledged that, in view of the lapse of time, it was not possible to establish at what time on 18 December 2010 the applicant’s legal guardians had been notified of his arrest but it was known that his mother had been present during his questioning before the investigator on 19   December 2010. The Government submitted that the applicant, who was a healthy young man, had been detained for less than twenty-four hours and, on his release, had a swollen cheek with no lasting consequences on his health. In their view, the applicant’s treatment had not attained the minimum level of severity to fall within the purview of Article 3 of the Convention. 44.     In reply, the applicant disagreed and reiterated his complaints. In particular, he resolutely denied any resistance to his arrest, the use by the police of any measures of restraint and, accordingly, any injury resulting from the use of any such measures. In his view, the reports on the use and the lawfulness of the use of measures of restraint during his arrest had been fabricated later to provide an explanation for his injuries. In addition, the applicant contended that the measures allegedly used against him for “holding and grabbing” him did not normally leave marks such as those observed on his cheek by a doctor. Moreover, the applicant pointed out that he had been served dinner the day following the day of his arrest whereas the applicable rules required food to be served to any person detained for more than six hours. Emphasising that he was of Romani origin and that he had still been a   minor at the time of his detention, the applicant considered that he had shown beyond all reasonable doubt that he had been subjected to treatment reaching the threshold required for a breach of Article 3 of the Convention. (b)     The Court’s assessment 45.     The Court has recently summarised the applicable case-law principles in its judgment in the case of Bouyid v. Belgium ([GC], no.   23380/09, §§   81 ‑ 90, ECHR 2015). 46.     The core of the present case appears to be the applicant’s allegation that, while at the county police station, and in combination with other factors, he was slapped in the face by the police officers questioning him. 47.     The Court reiterates that such treatment has been found to fall within the ambit of Article 3 (see Bouyid , cited above, §§ 100-12). It remains open, however, on the facts of the present case, whether the applicant was in fact slapped in the face in the circumstances he alleges. 48.     There is no dispute between the parties that the applicant was detained and that shortly after his release he was found by a doctor to   have a   slightly swollen cheek. At the same time, there is no indication that he had had a swollen cheek before his arrest. Nor has it been alleged or otherwise indicated that the swollen cheek was self ‑ inflicted or that the ill-treatment causing his swollen cheek was inflicted between his release and his examination by a doctor. 49.     It can therefore be concluded that the applicant’s swollen cheek was the result of measures taken against him by agents of the State between his arrest and release. 50.     The contention between the parties is as to precisely how the applicant’s condition came about. The Government on their part cited as the cause of his injury the measures used by the police for “holding and grabbing” him in order to overcome his resistance to arrest. The applicant, on the other hand, resolutely denied any such proposition and insisted that the police officers had deliberately slapped him in the face during his questioning. 51.     The Court observes that the controversy between the parties as to the cause of the applicant’s swollen cheek arose already at national level and that it continues before it with reference to certain arguments or pieces of evidence that do not appear to have been advanced and addressed expressly at the domestic level. It finds that, as such, the matter appears to fall primarily to be examined under the procedural head of Article   3 of the Convention. 52.     At any rate, the Court reiterates that it must be cautious in taking on the role of a first-instance tribunal of fact where this is not made unavoidable by the circumstances of a particular case (see McKerr v. the United Kingdom (dec.), no. 28883/95, 4 April 2000). 53.     In assessing the credibility of the applicant’s factual assertions, the Court finds it appropriate to scrutinise first of all the existing medical evidence concerning the applicant’s condition following his release from custody. The medical report of 19 December 2010 summarises his allegations as to the cause of his condition so that “he had been beaten by police officers the day before” and that he “had received a slap on the right cheek”. In terms of findings, the doctor observed that there was no haematoma, that the cheek was bruised, sensitive and slightly swollen, and that the injury was slight, with recovery time below seven days (see paragraph 23 above). 54.     The Court observes in particular that the doctor’s findings do not contain any further details as to the location, size and shape of the applicant’s injury and contain no elements, such as a state of shock (see, a   contrario , Bouyid , cited above, §§ 12 and 93), fatigue, dehydration or anything else to corroborate his allegations. 55.     Moreover, they contain nothing as regards the cause of the applicant’s injury. In particular, the Court notes that there is no indication in the doctor’s conclusions or otherwise that it could only have been caused by a slap in the face as alleged by the applicant or, conversely, that it could not have been caused by the means referred to by the Government. 56.     In addition, the Court cannot but note certain inconsistencies in the applicant’s submissions as noted by the doctor and made to the domestic authorities and before the Court. In particular, the medical report indicates that the applicant alleged that he had received a slap on the “right half of a cheek”, while the doctor’s finding of a bruise refers to a “cheek on the left”. Moreover, the applicant’s allegation that he had been beaten for three hours in the face and on the head, as a result of which he had bruises (see paragraph 26 above), and that he was slapped and punched in the head (see paragraphs 11 and 22 above) is contradicted by his allegations as recorded by his doctor that he had been slapped in the face and the finding of that doctor that there were no haematoma (see paragraph 23 above). 57.     The Court further notes that the Government have furnished an   alternative explanation for the applicant’s condition and have submitted documentary evidence for a part of their explanation, in particular as to the alleged use of physical force to overcome the applicant’s alleged resistance during his arrest. The applicant, for his part, disputed the Government’s version and submitted that the reports on the use and the lawfulness of the use of measures of restraint during his arrest had been fabricated later to provide an explanation for his injuries. In that regard, however, the Court notes that the documentation produced by the Government appears to be detailed and systematic while the applicant’s contention has been general in terms and without any evidence in its support. 58.     Furthermore, the Court observes that, although the applicant’s alleged ill-treatment took place during his detention between 18 and 19 December 2016, he lodged an official complaint in that respect only after seventeen days, on 5 January 2011. In so far as he alleged that complaints on his behalf had been made earlier by his mother, the Court observes that he has offered nothing to support such allegations and that the Government’s claim that there is no trace of any such complaints has gone unanswered by the applicant. In addition, the Court notes that the applicant has produced no other elements to support his version of the impugned events such as, for example, a   statement from his co-accused. 59.     Thus, in view of all the circumstances, the Court considers that the explanation offered by the Government of the events underlying the applicant’s allegations is a plausible. Accordingly, it finds that it has not been established that the applicant was actually exposed to slapping in the face during his preliminary questioning at the county police station. 60.     It therefore cannot be concluded that the applicant was exposed to treatment contrary to Article 3 of the Convention. This finding is not altered by other aspects of the case, which the Court finds auxiliary to the principal aspect set out above and which have either not been established on the facts (denial of liquid, psychological pressure) or did not attain the requisite threshold for the legal protection under Article 3 of the Convention to be engaged (to some extent denial of food). 61.     As to the alleged discriminatory nature of the applicant’s treatment, the Court notes that it was complained of in very vague and general terms. It considers that, given the specific circumstances of the present case, such allegations may be of relevance under the procedural head of Article 3 of the Convention rather than under its substantive head. 62.     In these circumstances, the there is no need to determine the question of exhaustion of domestic remedies attached to the merits of the complaint under the substantive head of Article 3. This concerns in particular the possibility of claiming damages from the State under the Police Corps Act and the State Liability Act. 63.     In sum, there has been no violation of the substantive head of Article   3 of the Convention in the present case. 2.     Procedural limb of Article 3 of the Convention (a)     Parties’ arguments 64.     The applicant complained that the authorities concerned had failed to   carry out on their own initiative an effective, independent and prompt investigation into his credible assertion that he had been subjected to treatment that was incompatible with Article 3 of the Convention. 65.     By way of reply, the Government objected that the applicant had failed to pursue his Article 3 complaints properly, in particular by raising them during his questioning on 19 December 2010 and in his interlocutory appeal of 21   December 2010 against his charges. Likewise, no mention of any ill ‑ treatment had been made by his mother when she appeared before the investigator on 20   December 2010. 66.     In addition, the Government recapitulated the course of the investigation into the applicant’s criminal complaint. They pointed out that he had officially complained of ill-treatment for the first time two weeks after his release. The ensuing investigation had involved the examination of the entire case-file concerning the robbery of which he had then stood accused, the police records pertaining to his detention, medical reports, and oral evidence from all those concerned. In addition, the applicant’s allegations had not only been examined by the CIS but also, following his interlocutory appeals, by three levels of the PPS. The former was structurally and hierarchically separate from the Police Corps and was directly answerable to the Minister of the Interior, while the latter was a   separate structure responsible for, inter alia, supervision of the investigation authorities. In sum, the Government considered that the impugned investigation had been extensive, prompt, effective and independent. In the course of it, the authorities had properly examined all of the applicant’s arguments. 67.     The applicant disagreed and reiterated his complaints. In particular, he contended that his allegation of having been submitted to treatment incompatible with Article 3 of the Convention had been credible, inter alia, in view of the fact that he had been detained at the county police station in an irregular fashion for thirteen hours, and the ensuing investigation into his allegation had been neither effective nor institutionally independent. In addition, he submitted that he had had asserted his rights by lodging a   criminal complaint and by pursuing the remedy available in that respect and emphasised that the authorities had failed to pursue the investigation on their own initiative, despite his mother having complained about his ill ‑ treatment in person to the head of the county police station and by telephone to the CIS. 68.     In a further reply, the Government submitted that the only persons authorised to receive complaints in matters such as those obtaining in the present case were the heads of the county police and of the district police. Neither of them had had any records or recollections of having received a   complaint from the applicant’s mother, and there had been no mention of a   visit or any communication from her in the respective police records (see paragraph 21 above). In addition, relying on the findings of the Constitutional Court in its decision of 10 April 2012 (see paragraph 31 above), the Government contended that the applicant had had no legal right to have a third person criminally prosecuted. His right to lodge a criminal complaint had merely implied that he had the right “to have the complaint dealt with by a body authorised to do so”, and it had been treated accordingly. (b)     The Court’s assessment (i)     Whether the allegation of treatment incompatible with Article 3 of the Convention was credible 69.     The Court reiterates that where an individual raises an arguable claim that he has suffered treatment infringing Article 3 at the hands of the police or other similar agents of the State, that provision, read in conjunction with the State’s general duty under Article 1 of the Convention to “secure to everyone within their jurisdiction the rights and freedoms defined in ... [the] Convention”, requires by implication that there should be an effective official investigation (see, for example, El-Masri v. the former Yugoslav Republic of Macedonia [GC], no. 39630/09, § 182, ECHR 2012, with further references). The next stage in the Court’s analysis of the applicant’s complaint is an assessment of whether his allegations of ill ‑ treatment at the national level can be considered as credible. 70.     To that end, the Court observes that, according to the applicant, his grievances were first raised at the domestic level by his mother in the days following his release and that the authorities failed to act upon them proactively. However, as submitted by the Government and not opposed by the applicant, there appears to be no record of any such submissions having been made by his mother. In addition, the Court notes that the applicant himself has not substantiated his allegations that a complaint was lodged on his behalf by his mother. In these circumstances, the Court cannot but conclude that the applicant’s allegations that a complaint was made by his mother and not acted upon by the authorities have not been made out. 71.     Nevertheless, there is no doubt that an official complaint was made on the applicant’s behalf on 5 January 2011. In it, those allegedly responsible for his treatment were identified in some detail, the nature of the treatment allegedly inflicted on him was described, and a medical certificate attesting to his condition was submitted in evidence. The Court is of the opinion that, in assessing the credibility of the applicant’s allegations, it must take into account that the applicant was a   minor and that there were misgivings as to the regularity of his detention and as to whether his legal guardians had properly been notified of his custody, especially as all of those factors must have been known to the authorities at the relevant time. 72.     All in all, the Court has no difficulty in accepting that the applicant’s allegations of ill-treatment contrary to the requirements of Article 3 of the Convention were sufficiently credible to give rise to an obligation on the part of the authorities to investigate them in compliance with the requirements of Article 3 of the Convention. This conclusion is independent of whether or not the alleged ill-treatment has ultimately been made out before the Court because, in the event of ill-treatment of a person deprived of liberty at the hands of his or her captors, it is precisely the lack of a   proper investigation that often makes the ill-treatment impossible to prove. (ii)     Whether the investigation was compatible with Article 3 of the Convention 73.     The Court has summarised the applicable general principles in its Bouyid judgment (cited above, §§ 114-23) as follows: -   The essential purpose of an investigation required for the purposes of Article 3 of the Convention is to secure the effective implementation of the domestic laws prohibiting torture and inhuman or degrading treatment or punishment in cases involving State agents or bodies, and to ensure their accountability for ill-treatment occurring under their responsibility. -   Generally speaking, for an investigation to be effective, the institutions and persons responsible for carrying it out must be independent from those targeted by it. This means not only a lack of any hierarchical or institutional connection but also practical independence. -   Whatever mode is employed, the authorities must act of their own motion. In addition, in order to be effective the investigation must be capable of leading to the identification and punishment of those responsible. It should also be broad enough to permit the investigating authorities to take into consideration not only the actions of the State agents who directly used force but also all the surrounding circumstances. -   Although this is not an obligation of results to be achieved but of means to be employed, any deficiency in the investigation which undermines its ability to establish the cause of injuries or the identity of the persons responsible will risk falling foul of the required standard of effectiveness. -   A requirement of promptness and reasonable expedition is implicit in this context. While there may be obstacles or difficulties which prevent progress in an investigation in a particular situation, a prompt response by the authorities in investigating allegations of ill-treatment may generally be regarded as essential in maintaining public confidence in their adherence to the rule of law and in preventing any appearance of collusion in or tolerance of unlawful acts. -   The victim should be able to participate effectively in the investigation. -   Lastly, the investigation must be thorough, which means that the authorities must always make a serious attempt to find out what happened and should not rely on hasty or ill-founded conclusions to close their investigation. 74.     On the facts of the present case, in response to the applicant’s criminal complaint, the authorities interviewed him and his associates, as well as the investigator and the two police officers under suspicion. In addition, they examined the case file concerning the investigation into the alleged robbery and other documentary material. 75.     Although the applicant’s interlocutory appeals against the decision to   dismiss his criminal complaint and his constitutional complaint in this matter w
