An undisclosed number of gunmen on Wednesday evening attacked the Criminal Investigation Department office of the Abia State police command located in Umuagu in Umuahia, inflicting serious injury on three police officers.
While one was seriously macheted, the rest two were shot but no casualty was recorded.
The injured officers have since been rushed to the hospital for medical attention.
A source who spoke to our correspondent on the condition of anonymity said the armoury was also invaded, though it is not clear if arms were carted away.
The facility had been attacked previously and burnt down by unknown gunmen.
