- 33 The overcrowding at the Athens Airport facility was compounded by other deficiencies. In particular, the unit for male irregular migrants was filthy. Further, persons detained in this unit were not allowed to take a shower and several of them complained about access to toilets. None of the migrants detained at the Airport Centre were offered access to outdoor exercise, despite the average length of detention in this centre being approximately 10 days, as the facility had no yard. 66. At the time of the visit, the Filakio Centre was accommodating 316 migrants (308 men and eight women). Despite the Filakio facility rarely surpassing its official capacity, the CPT’s delegation observed that, at times, individual dormitories would hold many more irregular migrants than there were beds available. For instance, between 8 and 14 September 2009, up to 80 migrants were being accommodated in dormitory No. 4, which had 25 sets of bunk beds, while at the same time, other dormitories had empty beds. The explanation provided by the commander of the centre was that he preferred to keep the various nationalities together. In its report on the 2008 visit51, the CPT described the Filakio Centre in more or less positive terms. In the intervening period, some improvements had taken place in respect of recreation: on occasion, the large yard (formerly closed) was used, providing the migrants with an opportunity to play football or basketball. However, during the 2009 visit, the CPT’s delegation noted a particularly tense atmosphere between staff and migrants. Further, the CPT’s delegation received information that the detention conditions in this centre were at risk of deteriorating. Apparently, the Prefecture and the Region have accumulated large debts with private suppliers, which could affect the catering, fumigation, maintenance and cleaning of the facility. 67. The Venna facility has an official capacity of 222 and, at the time of the visit, was accommodating 201 male irregular migrants in five large dormitories. The facility was in the same unsatisfactory state as was observed in 2007; poorly lit, dirty and badly maintained, with broken window panes. It is noteworthy that on 8 August 2009, the local Police Union sent a letter to the Rodopi Regional authorities requesting a number of urgent measures to improve the hygiene and material conditions, including regular cleaning of the dormitories and the installation of a sick bay. The regional authorities apparently agreed with the requests but were unable to take any action due to a lack of financial means. Further, given the existence of two large yards, there was no justification for the detainees only being offered outdoor exercise every second day for two hours. 51 See CPT/Inf (2009) 20, paragraph 41.
