The Papua New Guinea opposition leader, Dame Carol Kidu, says something very worrying is happening on the streets of Port Moresby, with squads of police from the Highlands terrorising people.
In the most recent clash on Monday two local police were hospitalised after being set upon by up to 70 police from Mt Hagen.
This led to a statement by the police commissioner, Tom Kulunga, that politicians are splitting the force.
He says the squads from the Highlands have been brought in and are funded by politicians.
Dame Carol Kidu, who is also the MP for Moresby South, says she doesn't know if there is a political motive behind bringing in the police squads.
"One would tend to think that maybe it is, but I have to be careful what I say. Other people have also said to me lately, Look, why is there such an increase of ten-seater Landcruisers cruising around with plain clothes people in them, and some of us are feeling very uneasy about it, because my children witnessed a severe bashing in one of these vehicles, of someone being bashed by these plain clothes people."
