- 21 46. As was the case during previous CPT visits, in practically all the facilities visited the detainees were not offered any activities and spent their time sleeping and loitering around in their cells; not even reading material or board games were made available. In Filakio, due a to lack of staff, the large basketball and volleyball yard was not in use. A similar situation was found in the Mytilini and Petrou Ralli facilities. However, in some facilities, such as in the Thessaloniki Police Holding Facility, television sets had been installed in the corridors for the migrants to watch from their cells. This is positive, but access to television does not replace the need for the development of a proper regime, including, sport and recreational activities. Only in the Amygdaleza facility were efforts made to provide some activities; the doors of the dormitories were left open during most of the day and evening for the juveniles to make use of the activity room, where, as a rule, the juveniles would also take their meals together. The CPT reiterates its previous recommendation that the Greek authorities take the necessary steps to provide an appropriate range of activities for persons detained in the special facilities for irregular migrants and the police holding facilities. 47. The CPT has stressed in the past that any attempt to provide a suitable regime will fail if the special facilities for irregular migrants and the police holding facilities are not provided with sufficient and qualified staff23. At present, the staffing of the special facilities for irregular migrants and the police holding facilities is such that the officials concerned are unable to carry out functions other than basic surveillance tasks. For instance, on the day of the visit, at Filakio a shift of six border guards was responsible for 343 detainees and at Mytilini, with a detainee population of 720, there were five border guards on duty during the day. At both the Filakio and Mytilini facilities, a social worker had been appointed; however, not surprisingly, their presence had not had any noticeable effect. The CPT calls upon the Greek authorities to review the staff complement attached to each special facility for irregular migrants and police holding facility. d. food 48. The supply of food varied in the different establishments visited. For instance, in Thessaloniki, food and bottled water had to be bought from the daily sum available to the detainees (Euro 5.87) and many migrants complained that they could not afford more than two sandwiches a day. Police officers interviewed by the delegation confirmed this state of affairs. The CPT recommends that steps be taken to ensure that all persons detained in facilities for irregular migrants are offered sufficient food, including at least one cooked meal (preferably warm) per day. 23 See CPT/Inf (2006) 41, paragraph 71 and CPT/ Inf (2008) 3, paragraph 34.
