NCD Metropolitan Superintendent Gideon Ikumu said two people were reportedly killed in a fight between the Helas and Eastern highlanders in Erima yesterday.
Mr Ikumu said, the two groups mobilized and exchanged projectiles resulting in some injuries, before police intervened and stopped the fighting.
He said the NCD Homicide unit is now investigating these reported killings, but the community leaders must also step in to assist the police in their investigations.
Mr Ikumu said the leaders on both sides of the conflict must identify the suspects involved in the killings and bring them to the police.
The Metsup and his men spoke to the Helas underneath the Kookaburra Fly over before meeting up with the Marawaka community at Erima Mambu settlement yesterday.
In these meetings, the Metsup appealed for calm and said the police will do everything within its means to stop the fight from re-occurring.
