Provincial police commander David Yapu has slammed the "unethical and unacceptable behaviour of the drunken soldiers" who went on a violent rampage at the Manus Island detention centre on Good Friday.

Inspector Yapu said the soldiers assaulted refugees, his policemen, PNG immigration officers and service providers and caused extensive damage to property and vehicles.

More than 100 detainees have signed a formal complaint, accusing Australian Border Force and Wilson Security of failing to protect those injured during the rampage.

Inspector Yapu said the soldiers were retaliating after one of their colleagues was allegedly assaulted during an altercation between Navy personnel and refugees who were playing soccer in the Navy base that surrounds the detention centre.
