Police in Manus reported that the incident occurred at Levei village, Lorengau, at 6.30pm.
Provincial Police Commander, Chief Inspector David Yapu, said the deceased was confronted by the suspect when he was heading to get his fishing gear at Levei.
During that time, the suspect took out a small knife and stabbed the deceased on his upper left arm, where he started bleeding heavily.
“A community health worker attended to him but could not do much to save his life as he had already lost a considerable amount of blood.”
