Papua New Guinea's police commander, acting Commissioner Tom Kulunga, has urged the police force to clean up its act, saying more than half of legal claims against the state stem from police-related assaults.
Mr Kulunga says nearly half a billion US dollars of claims against the state stemmed from abuse, assault and ill-treatment of members of the public whom police have sworn to protect.
He says the proper management of discipline is important to enable police to achieve its goals.
Mr Kulunga made the comments at the launch of a booklet called a Guide for Police Conduct and Behaviour, which is distributed around the force.
The pocket-sized book provides a general guide to ensure police uphold human rights laws and humanitarian principles when dealing with the public.
