Timothy Onwuatuegwu took part in the
1966 military coup which overthrew Nigerian Prime Minister
Abubakar Tafawa Balewa while also killing many other Northern senior army officers. Onwuatuegwu was put in control of a small band of soldiers whose main job was to assassinate any Nigerian officer or politician they deemed a threat
Kaduna. Maj. Onwuatuegwu, personally led a detachment of soldiers to Brig. Samuel Ademulegun's house. Onwuatuegwu made his way up to the Brigadier's room where he was laying beside his wife. Upon seeing Onwuatuegwu enter the room, Ademulegun shouted at him "Timothy, what the devil do you think you're doing?". Onwuatuegwu told Ademulegun that he was under arrest. Ademulegun reached for a drawer beside his bed, and as he did so, Onwuatuegwu shot him dead in his bed, along with Ademulegun's wife who was laying beside him. Although the coup was stopped by General
Johnson Aguiyi-Ironsi both Onwuatuegwu and his superior Major
Chukwuma Kaduna Nzeogwu were able to control the northern portion of
Nigeria for a few weeks. Both Onwuatuegwu and Nzeogwu were arrested by Nigerian police officers in early February but were not executed which outraged many Northern civilians. For an entire year Onwuatuegwu was in an
Enugu prison until May 30, 1967 when he was freed by Biafran leader
Odumegwu Ojukwu. ==Biafra==
