Rufus was said to have committed the act inside the late father’s cashew farm at Ibillo, Akoko-Edo local government area.
He was alleged to have used a stone to hit his father severally after an argument inside the farm.
State Police Commissioner, Hakeem Odumosun, said late Usman told his son not to enter the farm again which made his son to attack him.
Rufus, however, denied hitting his father with a stone.
He said his father was chasing him around the farm with a cutlass and fell down hitting his head on a stone.
“I did not kill my father. He was pursuing me and he fell down. The stone was on the ground. My father died six days later at the hospital.”
Odumosun said the suspects would soon be charged to court.
