CAT/C/TUR/CO/3 video surveillance cameras and that such cameras are alleged to fail in many cases. The reported lack of funding to reduce overcrowding by means of the construction of new penitentiary institutions, the high number of vacancies of prison personnel (approximately 8,000) referred to by representative of the State party, the shortage of medical personnel and reported shortcomings in access to health care of ill prisoners in the State party, are also matters of concern to the Committee. The Committee further notes with concern that information on detention facilities can be subject to restrictions under the Law on the Right to Access Information (Law No. 4982) (arts. 2 and 16). The State party should take immediate measures to bring an end to the endemic problem of excessive pretrial detention and overcrowding in places of detention. Furthermore, it should continue its efforts to improve the infrastructure of prisons and police stations so as to provide protection against abuses. In particular, the State party should: (a) Encourage members of the judiciary to consider and implement alternative means to deprivation of liberty as a penal sanction, including by introducing necessary legislation to this effect; (b) Install video surveillance cameras throughout police stations and make video recording of interrogations of all persons questioned a standard procedure; (c) Undertake a legal review of articles 15-28 of the Law on the Right to Access Information (Law No. 4982) with a view to assessing their compatibility with the legal obligations under the Convention; (d) Continue efforts to fill the vacancies in penitentiary institutions so as to ensure adequate staffing of prisons; (e) Limit restrictions of privileges relating to group activities of prisoners in solitary confinement regimes to exceptional and well-defined situations only; (f) Address the shortage of medical personnel and ensure access to health care of ill prisoners, including by deferring sentences if necessary. Registration of detainees 18. The Committee is concerned at reports that suspects are held in police custody without being officially registered and, in this respect, notes with concern the vague provision in law that registration of detainees shall occur “within a reasonable time” upon arrest (art. 2). The State party shall ensure prompt registration of persons deprived of their liberty and specify in law the maximum time for when official registration pursuant to apprehension shall take place. Violence against women 19. The Committee is concerned at numerous and ongoing reports of rape, sexual violence and other forms of gender-based acts of torture and ill-treatment committed by security agencies, detention officials and law enforcement officers. While noting training and awareness raising programmes undertaken by the State party to address and prevent such acts, the Committee regrets the lack of information on measures taken to ensure accountability of perpetrators, including investigations, prosecutions and convictions of the perpetrators, as well as information on reparation and compensation, including rehabilitation, for victims as required by article 14 of the Convention. 9
