Acting NCD metropolitan police commander Brian Kombe told Loop PNG that he has dispatched vehicles to round up the buses and address their grievances at the Unagi Oval.
For now, buses are lining up along the Manu bus stop as well as the Manu roundabout.
Boroko is a sight of people walking while the main Murray Barracks and Three-Mile road area is clogged up with traffic. This is because all the buses have gathered at the Murray Barracks roundabout.
For now residents are advised to exercise caution while on the road as the situation is quite tense.
Police are yet to be on the scene.
The protest is reported to be related to the ethnic clash early this afternoon at Gordon market between the Koroba and Tari people of Hela Province.
Eyewitnesses said some of the PMV buses suffered damages during the incident.
