Two policemen were killed and two others sustained injuries in a clash between Soldiers and police officers at the Independent National Electoral Commission (INEC) Collation Centre in Jalingo, Taraba state capital, on Monday.
Witnesses said a minor disagreement between soldiers and policemen guarding INEC headquarters in the state snowballed into a crisis that lasted nearly an hour.
According to sources, soldiers, who sent policemen away from the INEC collation centre, later invaded police headquarters and chased away police officers on duty.
According to a source, injured policemen are currently being treated at Federal Medical Center, Jalingo.
Vehicles parked inside the police headquarters were reportedly vandalized during the incident.
Sporadic shots triggered panic among residents as shops, markets and houses were shut.
During a joint press conference, the police commissioner in the state, Suleiman Amodu, said a high-powered investigative panel would be set up to establish the cause of the incident.
The Commandant, 6 Brigade, Nigerian Army, Jalingo, Brig General Frank Etim, and the state Director of the Department of State Services (DSS) attended the conference.
