Report on the Performance of Activities of the National Preventive Mechanism for 2016 Detention Unit. For example, detention premises of Split-Dalmatia County Police Administration, which are located in the building’s basement, provide no separate area for spending time in fresh air, whereas Šibenik-Knin County Police Administration has no detention unit, which is why premises of police station within that police administration, are used. Most police stations provide rooms of inadequate size, with only a concrete or wooden bed frame with no mattress or bedclothes on it. A positive example are rooms in all police stations of Šibenik-Knin County Police Administration – the only exception being Drniš – which are neat, with mattresses and blankets provided. Rooms are deprived of daylight, although it is foreseen by the Ordinance and CPT standards. In most police stations, sanitary facilities are under video surveillance, whereby privacy of accommodated persons is invaded, which is contrary to the Standards. In most police stations (Makarska, Omiš and Drniš), sanitary facilities are under video surveillance, whereby privacy of accommodated persons is invaded, which is contrary to the Standards. A positive example are police stations in Kaštela and Knin, where partitions have been installed, thus preventing video surveillance system from covering toilet facilities. In the detention unit of Split-Dalmatia County Police Administration, video surveillance system has been installed in four rooms and along the corridors, but not in other parts of the building where persons deprived of their liberty are situated; on the other hand, even though a video surveillance system has been installed in Vis Police Station, it is currently out of service, as a result of which prisoners communicate with police officers in the on-call room, by summoning them. Situation is similar in other police stations as well, where video surveillance does not cover corridors or other areas where persons deprived of their liberty freely move; in addition, communication with police officers is performed by waiving at the camera, because there is no separate call bell system. In some police stations, rooms for provisional confinement dispose of no sanitary facilities and when needed, persons deprived of their liberty are taken to a toilet normally used by police officers. Despite earlier recommendations to the Ministry of the Interior, detention supervisors simultaneously act as officials of the operations and communications centre, which is not an acceptable solution because performing two duties may result in employees’ becoming overburdened. Pursuant to the Ordinance, detention supervisor is responsible for correct application of regulations on treatment of detained persons and is required to inform detained persons about their rights and obligations. Since in detention units, there are no detention supervisors who would be exclusively responsible for this type of tasks, it remains unclear to what extent they are able to overlook treatment of detained persons. Furthermore, the Ordinance does not foresee the possibility of powers being transferred to other police officers, which is for example the case in Šibenik-Knin County Police Administration. Because of several competences, detention supervisors can neither completely apply the Ordinance nor completely monitor treatment of detained persons, which represents an additional risk when it comes to inhuman or degrading treatment. 28
