The head of Papua New Guinea's Sexual Offence Squad says police are making every effort to show that abuse of women by police officers will not be tolerated.
Australia has announced funding for four new family and sexual violence units in PNG, to complement the existing six that were set up with AusAID money two years ago.
PNG suffers the region's worst levels of family violence and rape, with most women having experienced some form of domestic violence and 60 percent of men reporting having taken part in a gang rape.
Detective Senior Sergeant Tinol Pakiapon, who works in the capital Port Moresby, says unfortunately police officers are also guilty of beating and sexually assaulting women.
"It doesn't happen all the time but many suburban police stations are going through such experiences and I can confidently say we've actually prosecuted about four cases so far."
Detective Senior Sergeant Tinol Pakiapon says the women involved in those cases had gone to police to report being beaten or sexually attacked.
