A/HRC/27/43 69. OHCHR provided support to the follow-up visit of the Subcommittee on Prevention of Torture to Cambodia in December 2013. The purpose of the visit was for the Subcommittee to follow up on its earlier recommendations, particularly with regard to the establishment of an independent national preventive mechanism compliant with the Optional Protocol to the Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment. The members made unannounced visits to places of detention, including prisons, police stations and drug rehabilitation centres, met with the relevant authorities, and transmitted a confidential report to the Government. 70. OHCHR supported a visit by the Special Rapporteur on the situation of human rights in Cambodia in January and June 2014. The visits focused on assessing the progress made toward the establishment of an independent national human rights institution and following up on the recommendations from his previous four substantive reports, and will be reported on by the Special Rapporteur. 17
