adequate and effective control, custody and surveillance of the Penitentiary Center.5 In addition, owing to the characteristics of detention centers, the State must protect the inmates from the violence that, in the absence of State control, may occur among those deprived of liberty.6 8. In this regard, the Court notes that, when adopting the provisional measures in 2007 (supra having seen paragraph 1), the Penitentiary Center of the Central Occidental Region had a prison population of 1,448 inmates, with an installed capacity of 790 according to data provided by the Inter-American Commission. Now, after the measures have been in force for six years, the Court notes that the number of detainees has increased and there were 2,456 inmates in August, 2012 (supra considering paragraph 6(m)) and 2,641 inmates in January 2013 (supra considering paragraph 5.h). Hence, a situation of overcrowding ranging from 310% to 334% existed in this prison, which evidently produces a climate of instability and confrontation within the prison.7 9. Second, the Court notes that, 58 individuals died and 95 were injured during the events of January 25, 2013 (supra considering paragraph 6.h). Moreover, the information provided reveals that the events originated from the fact that the State authorities had decided to conduct an inspection, a measure that had not been taken since 2009 (supra considering paragraph 5.h). In addition, different versions exist about how the deaths and acts of violence occurred, and the State has advised that it is investigating the facts (supra having seen paragraph 7 and considering paragraphs 5.c, 5.d, 5.k, 5.l, 6.c to 6.e and 6.k). 10. Without prejudice to whether the said events may be attributed to State agents or to the inmates of this prison, the fact is that, for the effects of these provisional measures, the acts of violence that occurred under the State’s supervision reveal the persistence of the situation of extreme gravity and urgency, and represent a situation of imminent risk to the life and personal integrity of the persons deprived of liberty in the Penitentiary Center of the Central Occidental Region, as well as of anyone who is in the said establishment. In addition to the recent acts of violence, the case file reveals that, according to the report of the Venezuelan Observatory of Prisons of February 17, 2012, during 2011, a total of 61 prisoners died and 240 were injured, and it was “the prison with the highest percentages of deaths and injuries during 2011, [owing] to a large extent to the sixteen (16) confrontations (coliseos) that occurred that year.” In the Court’s opinion, such events are inconceivable in the context of the protection that the 5 Cf.

All of this, to the detriment of both the prisoners and the officials who work in the penitentiary centers, owing to the difficult and dangerous conditions in which they perform their daily activities.
