This was revealed by the NCD Metropolitan Superintendent, Commander Ben Turi, around 2pm today.
A crew from this newsroom was present at Gerehu when the fight escalated just outside the block one area of Tete settlement.
Turi said this incident had occurred after a drunken brawl. He dubbed it as a trivial matter which should not have spiraled out of control.
However, the situation has now been contained and both parties have been urged to lay down their weapons for their sake and for the sake of residents in the neighbourhood.
Turi assured the parties that the Criminal Investigation Department is now on the case and the killings will be investigated thoroughly.
Those responsible will be appropriately dealt with, said Turi.
He is also calling out to witnesses to come forward to give statements on this issue.
