But a source said the men killed six suspected on Monday.
“They killed and burnt four suspects at Nkwo Amiyi. Mostly, those suspected to be cultists. They also killed two at Ifite Awka. Those ones were suspected handbag and telephone snatchers.
“The Bakassi Boys came mainly for alleged cults, which had taken over Awka town without any response from the police. I think they were invited by traders.”

Asked whether the police would be ready with such arrangement, the PPRO said ,”We are ready to work with any stakeholder in security.”
