CAT/C/GIN/CO/1 Alhousseine Camara, tortured in October 2011, Ibrahima Bah and Sékouta Keita, tortured in February 2012, Ibrahim Sow, tortured and deceased in February 2012, Aboubacar Soumah, subjected to torture and deceased in August 2012, Ballah Condé, tortured and deceased in December 2013, and Tafsir Sylla, tortured and deceased in February 2014. The Committee is particularly disturbed by the fact that these acts were committed during interrogations conducted by law enforcement officers while the victims were being held in custody and in the course of preliminary investigations for the purpose of extorting confessions (including by means of the “skewer technique”) (arts. 2, 10, 11, 12, 13 and 16). The State party should: (a) Take immediate and effective steps to prevent and punish all acts of torture. In this connection, it should conduct thorough, independent and impartial investigations without delay into all allegations of torture and ill-treatment, including the cases of the victims mentioned in the preceding paragraph, and bring the perpetrators of these acts to justice; (b) Train police officers and gendarmes in the absolute ban on torture and in all provisions of the Convention. The events in Conakry Stadium 10. The Committee is extremely concerned by the events that took place on 28 September 2009 in Conakry Stadium, which the International Commission of Inquiry on Guinea has qualified as crimes against humanity (S/2009/693, annex, para. 27). Despite the establishment of a “pool of judges” tasked with investigating and prosecuting the perpetrators of these incidents, the Committee is concerned by the slow pace at which the State party is working to determine responsibility for the acts of torture, summary executions, rapes, sexual abuse, instances of sexual slavery, arrests, arbitrary detention and enforced disappearances perpetrated during those events by law enforcement officers. The Committee is particularly disturbed at the massive sexual violence committed against girls and women during these events which has seldom been prosecuted, thereby contributing to a persistent climate of impunity. The Committee is also seriously concerned at the fact that certain individuals charged by the Guinean authorities with flagrant violations of human rights committed during these events are members of the current Government, namely Colonel Pivi, Minister for Presidential Security, and Moussa Tiegboro Camara, Secretary of State for Special Services, Drug Control and Organized Crime (arts. 2, 12, 13, 14 and 16). The State party should: (a) Ensure, as a matter of priority, that all the human rights violations committed during the events at Conakry Stadium, particularly the cases of torture and sexual violence, are systematically investigated, and promptly and impartially prosecuted, so as to guarantee to victims that the truth will be known, and justice and reparations granted, in accordance with the Convention and the Rome Statute, which Guinea ratified in 2003; (b) Ensure that witnesses are provided with adequate protection and financial resources under a witness protection programme; (c) Temporarily relieve of their duties, for so long as the investigation lasts, those members of the security forces who are suspected of having committed grave violations of human rights during the events at Conakry, while ensuring that the principle of the presumption of innocence is upheld; (d) Temporarily relieve of their duties all members of the Government accused of grave violations of human rights committed during the events at Conakry and in particular Colonel Pivi and Moussa Tiegboro Camara; 4 GE.14-05766
