Allegations a teenager beheaded her father with a bush knife after he raped her will be investigated, Papua New Guinea police say, amid reports community leaders are protecting her.
The 18-year-old is alleged to have chopped her father's head off after he repeatedly raped her last Tuesday night in their village in PNG's Western Highlands.
Media reports say the woman is being protected by community leaders in the area, who will not allow police to interview her on the grounds the man ''deserved to die''.
''A crime has allegedly been committed,'' police spokesman Dominic Kakas said on Monday.
''But a murder is a murder, it is a matter that will be investigated.''
Kakas said more information was being sought from Western Highlands police.
PNG's Post Courier newspaper quoted a pastor as saying the father, in his mid-40s, raped his daughter after her mother and three other siblings left to visit relatives.
Pastor Lucas Kumi said the man went to his daughter's room in the night and raped her repeatedly.
''The father wanted to rape his daughter again in the morning inside the house and that was when the young girl picked up the bush knife and chopped her father's head off,'' he said.
The report said community leaders were last night refusing to hand the girl over to police, vowing to protect her.
''The people and leaders in our area went and saw the headless body of the father after the girl reported the incident to the leaders and the people and told her story of why she had killed her father,'' said Kumi.
''The daughter did what she did because of the trauma and the evil actions of her father so that is why we have all agreed that she remains in the community.''
Violent crime is rife in PNG.
Brutality against women, including domestic violence and rape, is also endemic in the country.
Parliament last month voted to revive the death penalty in a bid to deter offenders after a series of high-profile grisly incidents.
On the outskirts of Mt Hagen in February 20-year-old mother of one Kepari Leniata was burned alive in front of a crowd following days of torture.
