CAT/C/KHM/CO/2 including with respect to hygiene and food supply. To this end, the Committee recommends that the State party apply alternative measures to imprisonment and ensure sufficient budgetary allocations to develop and renovate the infrastructure of prisons and other detention facilities. Furthermore, the State party should clearly frame and regulate the function and role of the “prisoner self-management committees” and ensure that cases of abuse and ill-treatment by such bodies are investigated and perpetrators punished. In addition, the GDP officials ignoring or condoning such acts should be held accountable, with the alleged suspects being subjected to suspension or reassignment during the process of investigation. The Committee also requests updated information on the circumstances surrounding the deaths of Kong La, Heng Touch and Mao Sok as well as information on investigations, prosecutions and convictions arising from these cases. The State party should also review current policies and procedures for the custody and treatment of detainees, including in police stations, ensure separation of female detainees from males and that female detainees be guarded by officers of the same gender, monitor and document incidents of sexual violence in detention, and provide the Committee with data thereon, disaggregated by relevant indicators. The Committee also recommends that the State party consider compiling a reliable and accurate profile of the prison population, including details as to the length of the sentence, the commitment of offence and the age of the offender, to help inform criminal justice policy decisions.

In addition, the Committee notes with particular concern allegations of a consistent pattern of arbitrary detention and abuse in Prey Speu between late 2006 and 2008, including torture, rape, beatings, reported incidences of suicide, and even reported killings committed by social affairs guards against detainees, The Committee is further concerned at the lack of information as to any initiative on the part of the State party to undertake a thorough investigation into such allegations. (arts. 2, 11 and 16) The Committee urges the State party to put a complete end to any form of arbitrary and unlawful detention of persons, especially in Social Affairs Centres, including Prey Speu. The State party should ensure that all relevant governmental departments respect the right not to be arbitrarily detained on the basis of social status in the view of the Government and without any legal basis and judicial warrant. The State party should also ensure that officials/guards and others involved in arbitrary detention and abuse are immediately investigated and prosecuted for such acts and that redress is provided to victims. The State party should, as a matter of urgency, conduct an independent investigation into the allegations of serious human rights violations, including torture, in Prey Speu between late 2006 and 2008.
