The applicant alleged that, in the period from 21 to 26 April 2017, he was detained unlawfully, in particular because his detention had been unrecorded and had been effected without a prior court order. He also alleged that, from 21 to 24 April 2017, he had been ill-treated while in police custody and there was no effective investigation in that respect. According to the letter of the prosecutor’s office of 13 January 2021 addressed to the applicant, on that date the investigation in respect of his alleged unrecorded detention and ill ‑ treatment was still ongoing. In March 2022 the applicant, who lived in Bakhmut (Donetsk Region), disappeared. The applicant’s mother, Ms Galyna Anatoliyivna Sydorenko, expressed her wish to continue with the application. QUESTIONS TO THE PARTIES 1.     Has the applicant been subjected to torture, inhuman or degrading treatment, in breach of Article 3 of the Convention?   2.     Having regard to the procedural protection from torture, inhuman and degrading treatment, (see Labita v. Italy   [GC], no.   26772/95, §   131, ECHR   2000-IV and Kaverzin v. Ukraine , no.   23893/03, §§   169-182, 15   May 2012), was the investigation of the applicant’s ill ‑ treatment complaints by the domestic authorities compatible with the requirements of Article 3 of the Convention?   3.     Was the applicant deprived of his liberty in breach of Article   5 §   1 of the Convention?
