The gunmen carted away arms and ammunition and also released other detainees in custody.
The two policemen who were killed were gunned down while trying to resist the gunmen. Two other officers that were critically injured during the attack are said to be responding to treatment at the Federal Medical Centre, Lokoja.
The gunmen who reportedly operated for over two hours unchallenged, were said to have set ablaze a vehicle parked at the station during the attack.
The spokesperson of the Kogi Police Command, Willy Aya, confirmed the incident but denied reports that there were fatalities from the attack.
