- 31 5. Action to be taken 51. In relation to the conditions of detention in police and border guard stations, the CPT calls upon the Greek authorities to take urgent steps to ensure that detained irregular migrants are transferred without delay to centres specifically designed to meet the requirements of this population, having due regard to the CPT’s criteria for places of detention for irregular migrants (see section D below). Similarly, strenuous efforts should be made to transfer all persons on remand or sentenced to imprisonment to an appropriate penitentiary establishment. Further, in the light of the severe shortcomings as regards the conditions of detention described in paragraphs 36 to 48 above, the CPT calls upon the Greek authorities to take concerted steps to ensure that: - - occupancy rates in police and border guard stations are revised so as to offer a minimum of 4 m² of living space per detainee in multi-occupancy accommodation; women are held separately from men; all persons detained have ready access to a proper toilet facility at all times, including at night; each detained person is provided with a clean mattress, clean blanket, clean bedding and a means of rest, such as a plinth or a bed; the provision of food for detained persons is adequate and appropriate, and includes one hot meal a day for persons detained longer than a few days; all detained persons staying longer than 24 hours are provided with a basic sanitary kit (including adequate rations of soap, washing powder, toilet paper, shampoo, shaving utensils and toothpaste, and a toothbrush), free of charge; all detained persons are provided with sufficient quantities of detergent to keep their cells clean; detention areas (including sanitary facilities) are maintained in an adequate state of repair and cleanliness; all detained persons have access to adequate lighting; all detained persons staying longer than 24 hours have access to a shower and to hot water; all persons detained longer than 24 hours are offered access to outdoor exercise every day. As regards health-care, reference should be made to the recommendation in paragraph 31 above. In respect of staffing, the CPT reiterates its recommendation that the Greek authorities give due consideration to establishing posts of specialised custodial staff for persons detained by law enforcement agencies.
