CAT/C/BGR/CO/4-5 mandatory training for relevant officials such as judges, law enforcement officials and prison staff (art. 10). The Committee recommends that the State party: (a) Prepare and implement training programmes to ensure that judges, prosecutors, law enforcement officials and prison staff are fully aware of the provisions of the Convention, in particular the absolute prohibition of torture, and that breaches will not be tolerated and will be investigated and the perpetrators prosecuted; (b) Develop training modules with the aim of sensitizing law enforcement officials and other personnel concerned against discrimination based on ethnicity and religion; (c) Provide medical personnel and others involved in the custody, interrogation or treatment of any individual subjected to any form of arrest, detention or imprisonment, as well as other professionals involved in the documentation and investigation of torture, training on a regular and systematic basis on the Manual on Effective Investigation and Documentation of Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (Istanbul Protocol) and ensure that such training is also provided for individuals involved in asylum determination processes; (d) Develop and implement a methodology to assess the effectiveness and impact of the training and educational programmes on the reduction of cases of torture and ill-treatment. Conditions of detention 21. While taking note of the State party’s plan to build new detention facilities and renovate existing ones, the Committee is concerned at the continued obsolete, insanitary and overcrowded conditions of detention in Bulgaria, which do not conform to international standards. It is particularly concerned about overcrowding which has reduced the average living space in many prisons to only 1 m2 per detainee instead of the recommended standard of 6 m2 and that some detainees are forced to sleep on the floor; that no new detention facilities have been built and that few were renovated; that, owing to budgetary restrictions, there is no improvement in the prisoner-staff ratio; that the Ombudsman highlighted in 2009 the need for reform of the prison system, expressing concern that the funds earmarked for renovation of prisons in accordance with the Strategy for Reforming Places of Detention (2009–2015) were drastically reduced in 2009 and 2010; and that material conditions such as access to drinking water, hygiene, electricity, the use of toilets, quality and quantity of food, purposeful activities and exercise do not conform to international standards (arts. 11 and 16). The Committee recommends: (a) That the State party strengthen efforts and increase funds in order to bring the living conditions in detention facilities to conform to international standards such as the Standard Minimum Rules for the Treatment of Prisoners; (b) The accelerated implementation and increase in funds for the Strategy for Reforming Places of Detention (2009–2015) and for the 2010 Programme for Improvement of Conditions at Places of Deprivation of Liberty; (c) The adoption of specific time frames for the construction of new prisons and renovation of existing ones and increase the number of staff in all facilities; (d) The increase in the budgetary allocations for basic amenities provided to detainees, including access to drinking water, food, electricity, hygiene and sanitation, and to ensure sufficient natural and artificial light, as well as heating and ventilation 8
