The three officers were together and had been in a bar before they argued and stepped out. Police say one of them pulled out a gun and shot the first colleague injuring him.
When the other one tried to intervene, he was shot and died instantly. It was then that officer turned the gun on himself and blew up his brains. The injured officer is in hospital in a stable condition. It is not clear what the officers were arguing over but a probe is ongoing.
Two more villagers were last night killed by Somali bandits in Mwingi in the ongoing fight over grazing pastures. This was after five camels had been slashed to death in ongoing tension over fields in the area. This increased to four, the number of people killed in the area since Monday night.
Tension remains high in the region after several houses were also burnt. Police have been ordered to drive away the Somali herders in the area as part of efforts to contain the violence. More officers have been sent to the area to contain the situation
