- 40 80. At Corfu Prison, the first three cells on K Wing were designated for prisoners serving a disciplinary sanction of solitary confinement. They were also used for persons who needed to be taken off the other wings for protection purposes and also, more recently, for persons who had tested positive for the SARS-CoV-2 virus. The three cells were in an appalling state of hygiene and dilapidation. The cells measured less than 6m², including a 1.5m² raised concrete plinth at the back of the cell where the unpartitioned floor level toilet was located. There was no running water in the cell although staff claimed that the flush could also be used for drinking water and cleaning purposes. The cells had no access to natural light as the barred window had been covered over with a screen from the outside and while one cell had a bright artificial light which apparently was not turned off at night, another cell (no. 2) had no functioning artificial light; the person accommodated in that cell for two weeks at the time of the visit had spent almost all his time in the dark. Further, the persons located in the disciplinary cells were not offered one hour of outdoor exercise every day. At the end of the visit, the CPT’s delegation invoked Article 8, paragraph 5, of the Convention and requested that the Greek authorities close the three disciplinary cells until such time as they have been completely renovated. By communication of 7 January 2022, the Greek authorities informed the CPT that the three cells in question had been taken out of service on 6 December 2021and that funding was being sought for their complete renovation. The CPT welcomes this rapid reaction by the General Secretariat for Anti-Crime Policy and would like to be informed about the renovation of the cells and when they intend to be brought back into service. 81. At Nigrita Prison, the conditions observed in the separate 10-cell segregation unit had been improved since 2019, with the unit having been recently painted and the in-cell sanitary fixtures repaired. At the time of the visit, the unit was accommodating one person who had tested positive for Covid-19, six persons in five cells who were in quarantine, two persons in one cell who had been involved in a fight on the wings and were now ostensibly on protection, and one person who was considered vulnerable with mental health issues. As in 2019, the unit was only supervised remotely by CCTV.42 The Covid-19 positive persons and the six persons in quarantine were not offered any out-of-cell time during their period of confinement. The two persons on protection shared a cell, with one of them sleeping on a mattress on the floor and were unlocked during the day and able to roam the corridor but they were not however offered access to the outdoor exercise yard. There was no staff supervision when the meals were distributed by prisoners to the cells via the hatches in the doors. Further, there was still no register on the placement of prisoners in the segregation unit nor any daily log to record all movements of prisoners in and out of their cells. The CPT recommends that the Greek authorities ensure that all persons placed in a segregation unit are offered a minimum of one hour of outdoor exercise every day. Further, the unit should always be supervised by staff when occupied and a register established to record all placements and movements within the unit. 42 It was unrealistic to expect the single officer responsible for Wing E and its 140 prisoners to also supervise the segregation unit.
