6 It is necessary to develop a system of continual training on human rights for judges, prosecutors, decision-makers and all officers directly treating persons deprived of liberty in the Republic of Serbia, particularly trainings on prohibition of torture and other forms of abuse. The conditions for police detention in certain police stations have been improved, but there is still a large number of inadequately equipped custody cells in certain police stations, i.e. They are not compliant with the applicable standards. The police interrogate suspects in rooms which do not have audio and video surveillance equipment. In Conclusions 73. of the National Assembly of the Republic of Serbia of 23 October 2014 states: “With regard to the assessment of the Protector of Citizens that many existing custody cells in police stations are not compliant with the minimum standards of the European Committee for the Prevention of Torture regarding necessary accommodation conditions, the National Assembly orders the Government to allocate necessary funds for construction or refurbishment of custody cells in police stations in accordance with the applicable standards in budget proposal for 2015.” In spite of recommendations by NPM, the applicable Instructions on Treatment of Persons brought in by Police and Persons in Custody of the Ministry of Internal Affairs has not been improved and in accordance with its provisions, which are not compliant with the applicable standards, police officers are mainly present during medical check-ups of detained persons; the installed video surveillance systems invades the privacy of detained persons in a large number of cases (toilets are also under video surveillance); police officers mainly put handcuffs on detained persons during transport. In Conclusions 73. of the National Assembly of the Republic of Serbia of 23 October 2014 states the following: “With regard to the assessment of the Protector of Citizens that the Instructions on Treatment of Persons brought in by Police and Persons in Custody are not compliant with the applicable regulations and standards and decisions of the European Court of Human Rights (use of physical restraint, presence of non-medical staff during physical examinations, lack of duty to install alarms, authorisations of control mechanisms etc.), which results in dilemmas for police officers regarding exercise of police authorities and divergent practices in their actions, the National Assembly orders the Ministry of Internal Affairs to make the Instructions on Treatment of Persons brought in by Police and Persons in Custody compliant with the applicable regulations, standards and decisions of the European Court of Human Rights.” There is still an impression that detention is often too readily ordered, that its duration is excessive and that courts rarely order measures such as bail bonds, which provide an effective alternative to detention. The circumstances surrounding the enforcement of detention measures, the violation of the presumption of innocence of detainees and the conditions in which such measures are enforced constitute a sort of punishment before sentencing. During the reporting period, the situation improved significantly with regard to overpopulation of detention units. Most detainees have the space of minimum eight cubic meters and four square meters at their disposal in dormitories. Although many detention facilities have recently seen adaptation and refurbishment, some rooms in detention units are dilapidated, worn-down and unclean. Rooms are not sufficiently aired, which makes the position of non-smokers particularly difficult because they are placed in the same rooms with smokers. In certain rooms natural light is insufficient, while artificial lighting is poor. The problem in the system for enforcement of detention measures in Serbia is that detainees mainly spend the whole day indoors, locked up in their cells/dormitories. Detainees are as a rule not allowed to spend spare time during the day outside of their cells, in communal areas with other
