The source said the militants ambushed Lieutenant AC Oguntoye and his colleagues on their way to Gubio from a shooting range competition in Monguno. The officers were pinned down by terrorists in Magumeri where they razed down houses, including a police station in the town.
The militants rode into the area in 10 utility vehicles, shooting and attacking military formations. A press release from the Nigerian police stated that a police Sergeant Haliru Aliyu was also killed in the attack while another sustained leg injury from gunshots.
A spokesperson to the Nigerian army later said the insurgents who were being shielded by members of the Magumeri community.
