CAT/OP/POL/ROSP/1 treatment. The Subcommittee recommends that the State party take measures to eliminate this and any other similar practices in its police stations. 66. In addition, the Subcommittee is concerned that persons in police detention do not have the chance to spend any time outdoors and that none of the police establishments visited possessed an exercise yard. 67. The Subcommittee recommends that the State party ensure that all persons in police detention are afforded time outside their cells, including for exercise and to breathe fresh air, for a minimum of one hour daily. (b) Transportation standards 68. Upon examining police vehicles at one police station, the delegation found them to be too hot for transportation, while observing that not all police vehicles were equipped with air-conditioning and seatbelts. Several detainees interviewed by the delegation complained that during transportation, they were handcuffed behind their backs or the cuffs were too tight. Upon examining the wrists of several detainees, the delegation observed red linear, parallel excoriations, consistent with their allegations. At one police station, the delegation observed that a detainee who was being prepared for a transfer was put in ankle cuffs. 69. The Subcommittee recommends that the State party ensure the safe transportation of arrested or detained persons, in accordance with traffic safety rules and regulations. B. Prisons 70. The Subcommittee observed that although Poland’s correctional system nominally differentiates between prisons and remand facilities, in reality, a mixture of convicted inmates and remand detainees can be found in both types of facilities. In the course of the visit, the delegation visited a total of seven correctional facilities: four were formally designated as prisons, and three as remand prisons (see annex I). 1. Ill-treatment 71. The delegation did not discover corroborated evidence of ill-treatment at correctional institutions in Poland. However, the Subcommittee is concerned at allegations that in some penitentiary institutions prison officers use violence to mould first-time offenders into submissiveness. The delegation also heard several allegations of verbal abuse and rude behaviour against inmates. 72. In addition, the delegation heard an allegation of collective punishment at Wrocław Prison 1 in the form of solitary confinement administered to a group of 10 inmates belonging to the “subculture” – an informal association of inmates with historic roots in prisons across Poland that maintains its own rules and norms. Reportedly, a fight had broken out between two of the inmates; however, all the inmates were sanctioned because they refused to give testimony in relation to the incident. 73. The Subcommittee recommends that the State party prohibit the use of collective punishment in its detention facilities through law and in practice, in line with rule 43 of the Nelson Mandela Rules. 74. In addition, the Subcommittee is concerned by several allegations of racially motivated harassment and discrimination against inmates who are foreign or appear to be. At one facility, a national of Ukraine reported that money sent by his family was not reaching his prison account, in addition to his working without pay at the prison. 75. At the same facility, female inmates complained that only half the money deposited by their families was reaching their accounts. Numerous complaints were heard by the delegation at the women’s section (Ward K) of Wrocław Prison 1 concerning food of a low nutritional or hygienic quality, reprisals against inmates who complained, verbal harassment, poor heating in winter and no access to laundry service. On the basis of those complaints, the Subcommittee is concerned that the conditions of detention result in de facto discriminatory treatment of women in that facility. Women also claimed that at night, their building was locked and the key was kept in the main administrative building of the prison, meaning that 11
