(Compass) – Opposition to Christian evangelism in Nigeria has resulted in the murder of Sunday Nache Achi, a fourth-year architectural student at Abubakar Tafawa Balewa University in the northern city of Bauchi . University representatives earlier expelled students Abraham Adamu Misal, Hannatu Haruna Alkali and Habakkuk Solomon for distributing a Christian leaflet that compared the teachings of Jesus with Islam. Muslims students at the nearby Bauchi Federal Polytechnic threatened two Christians with death before the pair was expelled from the school for similar evangelistic activities. Abducted from his room by masked assailants dressed in jihad style, Achi was strangled to death sometime in the early morning hours of December 9 and his body abandoned next to a mosque. Bauchi state Governor Alhaji Adamu Muazu promised a full investigation; however, authorities have not yet arrested any suspects in the murder.
