The relatives of four Papua New Guinea youths allegedly shot by police in Madang more than two months ago want to know why there has been no police investigation.
The Post Courier reports that the four died allegedly after a protest following the beheading of a teacher at Bau primary school in Madang on April 2.
The youths' relatives have asked the provincial police commander, Ben Neneo, about the lack of action.
They want to know why the police personal allegedly involved have not been suspended.
They have also demanded a coronial inquest be held.
Mr Neneo said the delays in the investigation were due to a lack of cooperation from locals.
