Police officers have taken over the police training college in Papua New Guinea to demand payment of promised allowances for providing security for Pacific Islands Forum leaders.
Around 150 Highlands mobile squad officers, were brought to Port Moresby for last week's Pacific Forum meetings.
The officers have set up road blocks at the Bomana Police College outside the city and closed the facility.
A police spokesman said the Deputy Police Commissioner Gari Baki had visited the officers and assured them their allowances would be paid.
Negotiations between the protesting officers and senior police are said to be continuing.
