- 18 - 26. As far as Piraeus Transfer Centre is concerned, conditions remained squalid, a state of affairs already noted in many previous CPT reports. The Committee was very pleased to learn by letter received on 12 January 2006 that the centre had been closed down. ii. border guard police stations 27. The conditions in the border guard stations visited were, on the whole, acceptable for short periods. At Tychero the two cells (35m²) had good access to natural light and ventilation, and mattresses and blankets were available; however, the toilet and shower area was filthy and without any lighting. In Soufli the two cells (54m²) possessed concrete plinths with 16 mattresses and clean blankets in both cells; access to ventilation and natural light was good, and the integral sanitation was particularly clean. In Iasmos the two cells (15m² and 20m²) had good access to natural light and ventilation, but the sanitary facilities were dirty. The facilities at Ferres border guard station have improved significantly since the CPT’s last visit in 1999; the two cells in use, one for men (45m²) and one for women (29m²), were well ventilated and had good access to natural light; however, the toilet and shower facilities were filthy. The delegation also noted that the 15 men in detention at the time of the visit had access to only 12 mattresses. The delegation was informed that the remaining two cells were used for storage; certainly, in their current condition, the cells were totally unfit for detention. The delegation noted the absence of heating devices in the detention facilities in Ferres and Iasmos, and the CPT would like to be informed about the arrangements for heating these facilities during the winter months. The delegation observed that irregular migrants, especially family units and women, could be held up to three months in Ferres and Iasmos stations. Given the lack of appropriate facilities and infrastructure in these border guard stations, including untrained custodial officers, nobody should be held in these establishments longer than a few days (cf. paragraph 31 below).
