A/HRC/30/59 violations are reported, the authorities must protect victims against further harm, prosecute the alleged perpetrators and provide reparations. 78. On 4 June, MINUSCA issued a statement according to which a member of its forces deployed in the east of the country had been implicated in all egations of exploiting and sexually abusing a young girl. The statement reports that MINUSCA took immediate measures to protect the victim and provide appropriate care. The statement also indicates that the United Nations requested that the Government of t he troop-contributing country concerned open an investigation as soon as possible. 79. On 5 June, the Office of the United Nations High Commissioner for Human Rights (OHCHR) issued a statement 14 regretting the lack of progress in the investigation of allegations of enforced disappearance, torture and extrajudicial killings of at least 11 people, including 5 women and 1 child, concerning the contingent of the Congo of the African-led International Support Mission to the Central African Republic (MISCA) 15 in Boali, a small town about 80 kilometres north of Bangui. OHCHR asked the competent authorities, including the African Union and the Governments of the Central African Republic and the Republic of the Congo, to carry out without further delay an impartial, effective and transparent investigation in order to clarify the fate of the persons concerned, bring those responsible to justice and provide reparation to the victims. 80. On 10 June 2015, MINUSCA issued a statement concerning the excessive use of force by peacekeepers deployed in the west of the country. According to the statement, United Nations soldiers allegedly beat four individuals suspected of criminal activities and arrested them at the request of local authorities, resulting in the death of two of the individuals and severe injuries to a third. 81. The Independent Expert welcomes the establishment by the Secretary -General of the United Nations of a panel of experts to conduct an independent external review to determine how the United Nations system followed up on those allegations. She is still concerned about the lack of diligence shown by the authorities involved in following up on these serious allegations of human rights violations, which are absolutely prejudicial to the protection of vulnerable persons, and calls for faster action to prevent abuses and, in cases where violations have been committed, hold the perpetrators responsible and ensure that the victims are protected. IV. Combating impunity 82. Significant strides were made in late 2014 and early 2015 in the fight against impunity, with the arrest of three important leaders of rebel groups. With the arrest and transfer of Baba Ladé to Chad in December 2014, Dominic Ongwen to the International Criminal Court in January 2015 and Rodrigue Gaïbona, also known as Andilo, who was detained on 17 January 2015, the transitional authorities have sent strong signals of their willingness to combat impunity. 83. However, many challenges remain, particularly relating to the insufficient staffing and resources of the police and gendarmerie, criminal police and the judiciary, and the inadequate number of prisons. In addition, victims are reluctant to file complaints with the police in situations where complainants are not of the same religious or ethnic group as the law enforcement personnel. __________________ 14 15 16/22 www.ohchr.org/EN/NewsEvents/Pages/DisplayNews.aspx?NewsID=16043&LangID=E.
