Police say a former local level government politician in Chimbu in Papua New Guinea was murdered at the weekend when on his way home from a political gathering.
44-year Wamna Gun was the former president of the Kup Local Level Government.
The Election Operations commander, Inspector Michael Wellsh, says Mr Gun was set upon by supporters of another candidate near Druamugl village on Saturday night.
His beheaded body was found in a nearby creek on Sunday morning.
Mr Wellsh says four candidates are contesting the Kerowagi seat held by the Defence Minister Guma Wau, and Mr Gun was publicly supporting one of the candidates.
He says the attack has been linked to supporters of the other three candidates and police have some leads on the perpetrators.
