An army corporal attached to the Special Task Force (STF) maintaining peace in Plateau, on Monday allegedly killed a police inspector at a check point in Mikang, Plateau.
Mr John Onuigbo, Plateau Police Command Public Relations Officer, confirmed the incident to the News Agency of Nigeria (NAN) on Tuesday in Jos.
He said that the incident happened "at about 2 p.m. on Monday".
"Preliminary investigation revealed that the two men had a 'little altercation' that led to the shooting," he said.
"The matter is already under investigation at the State Criminal Investigation Department, Jos. We want to find out why the corporal shot the inspector.
"The army corporal has been arrested and he is in detention with the appropriate authority.
"As soon as the matter is completed, he will be charged to court," the police spokesman said.
The police official, however, did not give the identity of the persons involved.
"Such details will be made public in due course," he said.
Efforts to speak with STF spokesman, Capt. Salisu Mustapha, proved abortive as calls to his line were neither picked, nor returned.
An STF source told NAN that the spokesman was on the entourage of the STF Commander, Maj.-Gen. Henry Ayoola, on a peace sensitisation tour to some crisis-prone communities in the outskirts of Jos.
