The assassins stormed into the hostel of Mubi Polytechnic and according to a lecturer of the institute, they had asked the students to identify themselves by name. He said the invaders did not explain any reason for the identification process and spared some of the students. The others were either shot or stabbed. Some sources said the grave incident continued for five hours, starting on Monday night.
It was also learnt that the students were recently asked to leave the college in a statement which was suspected to have written by radical Islamist sect Boko Haram, which is responsible for a series of killings in the oil-rich country.
On Saturday, three students were killed outside a university campus, located 100 miles from Maidiguri, the sect's spiritual base. The outfit is against western education and influence and has been indulging in violence since 2009, when its leader Mohammad Yususf was killed by the police.
National Emergency Management Agency sources said it could not be confirmed whether the gunmen who caused the latest massacre were members of any extremist group. Police were also probing whether the incident was a result of the continuing political feud inside the college.
