- 41 In this connection, the CPT recommends that, following a needs assessment and a period of in-depth consultations with all interested parties, the Ministry of Justice produce a strategic plan for the recovery of the prison system that covers the following areas:  the mission of prisons and the values to which prison staff will work;  the size of the prison estate and the range of the prison types that it will include;  the range of activities that will be provided and the amount of access that detained persons, including those on remand, will have to them;  the introduction of specific offender management programmes to assist prisoners in preparing for their return to the community;  the human resource requirement needed to run the prisons professionally (notably, prison officers), giving competence profiles for the key roles;  the role and input of the Ministry of Culture, Education and Religious Affairs in education-related activities;  the role and input of the Ministry of Health in the provision of health care, including as regards the staffing of health-care services in prisons;  financial projections over a five- to ten-year period, showing how the planned provision will be met within the resource levels available. 64. In the course of the 2015 visit, the CPT’s delegation visited Alikarnassos and Nafplio Prisons for the first time and carried out targeted follow-up visits to Diavata (Thessaloniki) and Korydallos Men’s Judicial Prison. A brief description of each prison is contained in section 3 below. It also visited Korydallos Prison Hospital (see section 6) and the Special Juvenile Detention Facility in Corinth Judicial Prison (see section C.2). 2. Ill-treatment 65. As was the case during the previous visit, the CPT’s delegation received almost no allegations of physical ill-treatment of inmates by staff. Indeed, in a number of prisons such as Nafplio and Korydallos Men’s Prison there is little daily contact with prison officers. 66. However, the CPT’s delegation found once again that inter-prisoner violence and intimidation were a serious problem in all the prisons visited. Cases of hospitalisation of inmates due to severe injuries inflicted by other inmates were a feature in every establishment. The CPT is compelled to reiterate that the existence of this phenomenon is directly linked to shortages of staff, resulting in control being ceded to groups of particular prisoners, often formed along ethnic lines, within the accommodation wings. These groups intimidate, bully and physically abuse other prisoners. The time has come for the Greek authorities to recognise the extent of the problem and to tackle it forcefully, notably by increasing staffing levels and introducing a dynamic security approach within prisons, and by rigorously investigating and prosecuting the perpetrators of interprisoner violence.
