A man sustained head injuries and a small shop was burnt in a clash that escalated over night at ATS Settlement in Port Moresby.
The fight started yesterday night after youths from Highlands harassed another from Oro, who was the son of a pastor, while being dropped off at the main bus stop.
The fight continued til daybreak.
A store owned by a Highlander was burnt down during the clash, however youths from Oro claim they did not burn it.
Market Stalls were also burnt down.
Those wanting to go to church or work in the morning were left stranded because no PMV buses or cars could enter the settlement.
Police were called in to ease the tension at night but when they left it started again.
This morning they were there in full force and to control the situation.
The Oro community says these harassments have been on going over the years since people from other province came and settled there.
They claimed that Alcohol and Drug abuse have been the main cause for these harassments.
Police called on leaders from both sides to come together and discuss peace alternatives.
The Oro people want those who instigated the fight to be arrested and for alcohol to be banned.
They also want no more buai selling and the markets left for selling food items only.
The owner of the burnt shop also wants those who burnt his shop to be arrested.
Five suspects have been handed over to the police by leaders from Highlands and are calling on those who burnt the shop to also be handed over.
Police say they and the leaders from both sides will appoint a day for all to come and have peace talks.
