Sources said the incident which happened inside the police college quarters of Borno Police headquarters in Maiduguri, has caused disarray in the college.
A senior police officer told Pointblanknews.com that the errant officer is currently being detained at the State Criminal Investigation Department (SCID).
“He and his wife have been having issues for some time now; we tried to settle it amicably, but he refused,” source said.
“The wife told her parents that the sergeant assaulted her; she moved her things out of his house. The wife left due to severe maltreatment by her husband.
“He started shooting and threatened to kill everyone. Unfortunately, he shot people, but six mobile policemen died and two others are currently receiving treatment at Specialist Hospital.
The effort to get reactions from police proved abortive as the line of the Police Public Relations Officer in Borno, was switched off at the time of filing this report.
