- 46 96. The CPT has stressed in the past that the duty of care which is owed by the prison authorities to prisoners in their charge includes the responsibility to protect them from other prisoners who might wish to cause them harm. The prison authorities must act in a proactive manner to prevent violence and intimidation by inmates against other inmates. Addressing the phenomenon of inter-prisoner violence requires that prison staff be alert to signs of trouble and both resolved and properly trained to intervene when necessary. The existence of positive relations between staff and prisoners, with a balance between security and a duty to care, is a decisive factor in this context. This will depend greatly on having an adequate number of staff present in detention areas (see paragraph 120 below). The CPT reiterates its recommendation that the Greek authorities devise a national strategy concerning inter-prisoner violence and intimidation, taking into account the above remarks. 3. Conditions of detention a. material conditions 97. Amfissa Prison, located in the centre of Amfissa Town, is cruciform in design and consists of a reception/visits area, six dormitories, two connecting courtyards, a kitchen and a chapel. The prison holds both remand and sentenced prisoners. On the day of the visit, the prison was holding 217 inmates for an official capacity of 80. Inmates are accommodated on two floors, each consisting of two large dormitories (68m²) and a smaller one (46m²). All the dormitories were severely overcrowded with not much more than 1.5m² of space per prisoner. In the larger dormitories, some 20 sets of bunk-beds were squeezed together; however, as there were more inmates than beds available, it was not uncommon to observe three inmates having to share two beds. Many inmates complained that they had had to sleep on a mattress on the floor for extended periods. In one of the smaller dormitories, which contained 13 bunk beds for 27 inmates, the delegation met a middle-aged man with serious respiratory problems who carried around his own portable oxygen supplies. This inmate had no bed and slept on the dormitory’s plastic table, which during the day was used for other purposes. In an upstairs dormitory, what appeared to be very small single-occupancy room (2m²) turned out to be a toilet area over which a mattress had been laid. In addition to the overcrowding, the dormitories were generally decrepit, in a state of disrepair and appalling hygiene. Floors were grimy, mattresses and bedding were infested with bed bugs, cockroaches were evident everywhere and a number of windows were broken, leaving certain inmates exposed to the elements as winter approached. The sanitary facilities were inadequate for the number of inmates, and there were complaints that one of the two toilets in each dormitory often did not function properly. Inmates complained that they were provided with insufficient quantities of hygiene products and had no means with which to wash their bedding and clothes. They also possessed no personal lockable space. 98. Chios Judicial Prison was described in the report on the 2005 visit67 and has not changed. At
