The attackers invaded the home of the police boss along Bank Road in the state capital to protest the alleged killing of two of their members by soldiers, reportedly burning vehicles in the compound as a result.
This is coming off the back of a week of unrest in the state with soldiers of the Nigerian Army clashing with members of IPOB and their leader, Nnamdi Kanu.
A detachment of the Nigerian Army had been present around the home of the IPOB leader on Tuesday, September 12, creating heightened tension with members of the group only days after soldiers clashed with them while trying to gain access to the group's leader's house on Sunday, September 10.
While reports indicated that soldiers had tried to gain access into Kanu's father's compound in Umuahia and shot at IPOB members who formed a human shield to keep them out, the army dismissed the claims and said the soldiers had been attacked with stones while passing through the residence in a new armoured carrier.
While reacting to the incident on Monday, September 11, Kanu accused Chief of Army Staff, Lieutenant-General Tukur Buratai, of trying to incite his group into arming themselves to deliberately provoke a war.
He said, "Nigeria is bringing war to us, we're not fighting anybody. It is Buratai and his men that are bringing war unto us.
"They want us to become armed so that the world can say that Nnamdi Kanu is leading a violent armed group, which is not the case. They're provoking us to war."
The clashes between the opposing sides led to state governor, Okezie Ikpeazu, declaring a dusk to dawn curfew that has been extended till Friday, September 15.
