The Papua New Guinea police commissioner, Tom Kulunga, has condemned the killing of a woman in Mt Hagen calling it 'shocking and devilish'.
20 year old Kepari Leniata was stripped naked, tortured with a hot iron rod, bound, doused in petrol and set on fire on a rubbish heap on Wednesday.
She had been accused of sorcery.
Police spokesperson, Superintendent Dominic Kakas, says they will arrest and prosecute the murderers but the commissioner wants a wider community discussion on how to tackle the issue of sorcery.
"As long as people believe in sorcery and they will tend to take violent action in relation to that we will still have such killings in relation to that. That is why the commissioner is concerned and he wants everyone to sit down and put their heads together and find a way to address this issue so that we can end or stop such senseless killings."
The Commissioner has suggested a special court for sorcery cases and thinks wider awareness through education will help stop the abuse.
