A Papua New Guinea member of parliament says the police commissioner Tom Kulunga needs to step in and order Highlands police in Port Moresby to return home.
A squad of Highlands' police has been accused of terrorising people in the capital for several months culminating in a clash earlier this week with local police.
MP Andrew Kumbakor says the Highlands police are mercenaries brought into Port Moresby by prime minister Peter O'Neill and his deputy Belden Namah to maintain what he calls their illegal regime.
Commissioner Kulunga says politicians are splitting the police force for their own ends but Mr Kumbakor says Mr Kulunga should go further and deliver the following message.
"Look I made a mistake. All of you policemen who came down from Hagen, there is no work for you. You go up and address the law and order problem in the Highlands. Here the NCD [National Capital District] police, who have got the numbers, can manage their own problems. So there is no need for these foreign policemen to come down here. There is no unrest here."
