A police inspector was shot dead in Adamawa State Tuesday, witnesses and the authorities said.
The officer was killed by a local vigilante group for refusing to stop at a checkpoint, while riding a motorcycle.
The military had last week placed a ban on commercial motorcyclists as part of efforts to check insurgency in the state.
The vigilante group attacked the officer in Ganye, southern part of the state.
According to a witness, Semsire Ayuba, the inspector, who was not wearing his uniform at the time of the incident, failed to stop when asked by the vigilante group to do so.
“It was after he refused to stop, one of them shot him,” the witness said.
Police spokesman, Othman Abubakar, said he did not have details of the attack, but confirmed receiving the report.
The military announced the ban of motorcycles across the state last week with effect from Monday, August 17.
