Papua New Guinea's acting deputy police commissioner and chief of operations, Fred Yakasa, says the police hierarchy is serious in holding officers accountable for their actions.
Mr Yakasa's comments come after first constable Paul Karl was committed to stand trial over a killing which sparked a riot in Kimbe, the capital of West New Britain province early this year.
Another three police had been charged with failing to act when an offence was being committed but this has been struck out due to insufficient evidence.
Mr Yakasa says there's overwhelming evidence of their involvement and the police hierarchy is in discussions with the State Prosecutor's Office to see if they can be committed on other charges.
