Abdi Mohammed Omar, known as Abdi Illey, former president of the volatile Somali region was arrested a few months ago for allegedly being behind the human rights violations as well as the ethnic and religious clashes that have happened in the region. Somali region is Ethiopia's second-largest but also one of its most unstable, and human rights groups have repeatedly accused Abdi's government of using its Liyu police force to carry out abuses. Other senior officials of the regional government were also arrested along with Ato Abdi suspected of the same crimes. Police have been investigating the case for months, compiling evidence and interviewing witnesses. During the fourth court session today, prosecutors announced they have completed the investigation and need more time to file a complaint. The Federal High Court allowed an additional thirteen days for the prosecution.
