A total of four Papua New Guinea police squads have been deployed to deal with tribal violence in the Bulolo township of the Morobe Province.
A total of 120 men from Mt Hagen and Goroko were flown into the Bulolo township on Sunday to join two squads already on the ground.
The Commissioner of Police, Tom Kulunga, says the fight has resulted in killings and damage to public and private properties and has been going on for far too long.
Mr Kulunga says he's calling on the leadership of the two warring people to come together and solve their disputes peacefully.
He says police will identify and single out those responsible, and let the law deal with them instead of having locals taking the law into their own hands.
Tom Kulunga says the police will remain in Bulolo for as long as is required to maintain law and order.
