The gunmen also desecrated the corpse that was being prepared for burial.
The incident caused people to scapper for safety.
The state Police Public Relations Officer (PPRO), DSP Tochukwu Ikenga, confirmed the incident to journalists on Saturday.
He said a burial was going on when some people suspected to be cultists invaded the area and started shooting.
“I do not have details of casualties now, but I will keep you informed once the picture becomes clear,’’ he said.
He said that the Commissioner of Police, Mr Echeng Echeng, immediately despatched a tactical squad comprising various units to the area to restore peace and order.
It was gathered that the 34-year-old man, identified as Ozo, whose funeral was holding at the time of the incident was killed on December 30, 2021, by suspected cultists at Amansea Area in Awka North.
“It was during the lying-in-state at the residence of the deceased that the suspected cultists arrived at the scene and started shooting at mourners,’’ a source said.
According to the source, those who sustained bullet wounds were taken to the Chukwuemeka Odumegwu Ojukwu Teaching Hospital at Amaku, Awka.
