The suspected armed robbers were said to have arrived in seven vehicles and stationed themselves in each of the banks around 4:30pm.
Channels Television crew who visited the scene reported that the doors were damaged, car windscreens shattered, vehicles burnt, and documents scattered on the floors of the affected banks.
One of the medical doctors at the General Hospital Offa who spoke behind the screen disclosed that 21 bodies were brought in around 6.00pm and nine of them were police officers.
At a private hospital also in the community, the doctor on duty confirmed the death of three victims while one was on admission.
