A/HRC/16/52/Add.4 per month, often related to drugs or suicide. Not all deaths in prison were duly registered and investigated. In relation to the allegation that not all deaths were duly registered and investigated, the Government informed that all deaths in the detention facilities are fully registered and investigated. Only deaths that occur in hospitals are investigated by the hospital and not by the detention facilities' authorities due to medical privacy. A male detainee, from Sudan, has been detained in the facility for three months for not possessing valid documents. There were sixteen persons in his cell. They used their own money to buy food and soap. They cleaned the toilets and showers themselves. A male detainee, from Palestine, had been detained in the facility for two months for not possessing valid documents. There were sixteen persons in his cell. The cell was very dirty, lots of insects and flies. Many people in his cell were here for 6 months to one year for not possessing valid documents. The telephone was not working. Four male detainees from Albania explain that the first and second floor of C Block was in lockdown because a fight had broken out between Arabs and Pakistanis and they believed an Arab man may have been killed. These things happen all the time. A number of people were injured, including one guard who was badly beaten. The guards ordered a lock down as a disciplinary measure. The prisoners shouted and banged on the doors for hours and setting fire to their clothes and hanging them out the window. Many were in the facility serving long sentences for drug offences. Block C- Section of vulnerable people In this block there are 23 detainees in cells of two beds each. The cell doors are open during the day, but the doors of the block, including the doors to the external secured yard, are all the time closed. As a result the detainees can not go out to breathe fresh air, practice any activity or see the sunlight at all. Two transgender persons from Greece were brought from Corfu to Athens for their court hearing three days earlier. They complained about the fact that the cell is overcrowded and very unhygienic. Also, they mention that the section of vulnerable persons is completely locked down all along the year, and that detainees cannot access the yard, because of an escape that happened in 2008. They therefore have to remain inside the small block all the time. They say that guards and detainees are respectful. The Government informed that the vulnerable persons in Block C of Korydallos Detention Facility were all pre-trials and held in separate cells for their own protection temporarily - contrary to the information provided by some detainees who mentioned they had been in these cells for a rather long period of time. The Government added that these two persons have already been transferred to other detention facilities, in individual cells, for serving their sentence. Block E - basement used for administrative detention This block comprises in its basement irregular migrants held in administrative detention. There are 3 cells of 16 people each. The door to the basement is open and detainees can at time access the ground floor, but they cannot go out on the yard. Some have beds; others sleep on the floor as it is overcrowded. The Government informed the Special Rapporteur on 3 March 2011 that the irregular immigrants held in the basement of Block E, are mainly immigrants for deportation to their countries but they have refused to cooperate with the competent authorities for issuing the appropriate travel documents. The Special Rapporteur noticed hundreds of bugs and cockroaches crawling under the mattresses, in the food and on the floor. The conditions of hygiene were very bad. The Special Rapporteur noticed that the detainees were very agitated and anxious. Also, several detainees had self-mutilation signs. 61
