A/HRC/16/52/Add.4 and Venna Migration Detention Centers. Due to the overcrowding in the facilities, the officers could not separate them from the other detainees. However, the Special Rapporteur recalled that this vulnerable group is at risk to be exposed to various forms of ill-treatment including sexual abuse when not properly separated from adults. 71. Furthermore, the procedure to identify minors, and assess their age and vulnerability appears to be completely inadequate as many juveniles reported being registered as adults. This may be explained by a general lack of trained staff and interpretation services. 72. Also, the Special Rapporteur came across a number of cases of ill-treatment of minors, corroborated by medical evidence. 73. Finally, the release of unaccompanied minors pending deportation puts them at significant risk for further abuse, including exploitive work and the risk of being trafficked, if they are not provided with adequate care and not registered in a tracking system.44 G. Women in detention 74. The Special Rapporteur generally found male and female detainees to be separated in the places of detention he visited. However, due to the recent influx of aliens over the Greek-Turkish border and the overcrowding of the facilities located in the Evros region, he found women detained with men at the border-guard stations of Feres and Soufli. 75. The women held at Venizelos Airport Police Station were held in much better conditions than the men. They were not in small, overcrowded and suffocating cells; they had room to move around and could access the shower and toilet facilities as they were located within their contained area. However, they complained about the lack of cleaning supplies and hygiene products. 76. Many women detained in migration detention centres were even more affected by the appalling conditions of detention and the lack of hygiene, as they had to take care for babies and small children. 77. In the Korydallos Women’s Prison the Special Rapporteur witnessed an atmosphere of extreme agitation and despair due to the slow criminal justice system and the conditions of detention. The detainees complained about long periods (up to 15 months) of pretrial detention, lack of access to free legal aid, and long prison terms for comparatively minor crimes, above all drug-related offences. The vast majority of the women detained were in remand because they could not afford bail. Detainees with a drug addiction received no adequate medical attention or access to substitute treatment. Many detainees had serious diseases, such as hepatitis C, HIV or multiple sclerosis, and were without access to basic medical assistance. The detainees complained that they had to pay for services which should be provided free of charge by the prison administration, such as toilet paper, soap, decent food, etc. This led to a feeling of powerlessness and discrimination among the detainees. 78. One of the most serious complaints received was the ongoing practice of intra-body searches. The Government reported that the practice of “vaginal searches” of female prisoners was abolished in September 2010. The Penitentiary Code (sect. 23, para. 6) provides the basis on which an intra-body search may be conducted, which says there must be “reasonable cause” to justify such a search. When there are violations of this provision, the Government informed that the competent Public Prosecutor is responsible for 44 18 Human Rights Watch report, 2008, “Left to Survive – systematic failure to protect unaccompanied migrant children in Greece, p. 103.
