Papua New Guinea's police minister says the government is determined to stamp out alleged violent practices among police.
The US-based group Human Rights Watch accuses the PNG constabulary of routine beatings and rapes of detainees including children.
Bire Kimisopa says the government cannot hide from the report.
But he says the government was working hard to change the police culture to eradicate such practices.
The police association president Robert Ali says the constabulary is a human organisation and therefore fallible.
"There are of course problems within the organisation. You are of course dealing with human beings, and human beings are sometimes you know, they can also step out of line. You find this in any organisation."
