- 19 At the time of the 2008 visit, there were 720 detained migrants in the facility for a capacity of approximately 300. By consequence, the detention conditions were abominable, with, for instance, more than 100 persons sharing two toilets and detainees having to share mattresses or sleep directly on the floor. Clearly, under such conditions, any attempt to maintain basic hygienic standards and, more generally, to offer acceptable social and medical care, is bound to fail. In fact, leaking toilet and shower facilities, poor ventilation, general squalor and an absence of daily outdoor exercise turn the conditions in the Mytilini Special Facility for Irregular Migrants into a health hazard for staff and detainees alike, and call for immediate emergency measures. The CPT recommends that the Greek authorities take immediate steps to provide appropriate living conditions in the Mytilini Special Facility for Irregular Migrants, in the light of the above remarks. 41. The Holding Facility of the Thessaloniki Aliens Police is located on the first floor of a building on the outskirts of Thessaloniki. On the day of the visit, there were 108 male detainees accommodated in nine rooms, each measuring approximately 60 m². All cells were equipped with toilet facilities and efforts were made by the detainees to keep their living quarters clean, using detergents provided by the authorities. There was sufficient access to natural light, via large windows, and the artificial lighting was sufficient. However, there were no beds in the rooms; the detainees slept on dirty mattresses and blankets placed directly on the floor. Further, there was no yard for outdoor exercise. The Special Facility for Irregular Migrants in Filakio opened in the spring of 2007. On the day of the visit, the facility held 343 irregular migrants, including 26 women and three young children. The detainees were accommodated in seven dormitories, including one secluded dormitory for women and young children. The dormitories had access to natural light and adequate artificial lighting, and were properly ventilated. All detainees were provided with a bed and blankets. However, due to the rooms being cramped with bunk beds22, there was a severe lack of living space. The confined atmosphere was exacerbated by the limited possibility for the detainees to enjoy outdoor exercise; despite the existence of suitable yards, they were offered access to fresh air for a mere 15 to 20 minutes every day. In contrast to many other facilities visited by the delegation, there appeared to be an effective cooperation between the police, region and prefecture in the Filakio facility. Consequently, the facility was properly maintained, there were no problems with the provision of hygienic items such as detergents, toilet paper and toothpaste, and mattresses and bedding were reasonably clean and in plentiful supply. The Filakio facility is proof that when the region, prefecture and Hellenic Police Force cooperate effectively, it is possible that a large detention facility can remain well-maintained and reasonably clean. 22 For instance, dormitory n° 5, with a surface area of approximately 108 m², contained almost 80 beds.
