A police officer attached to Parliament shot and killed his colleague in an altercation in a bar in Gigiri, Nairobi.

The three were among a group in a bar at the Gigiri police lines when they disagreed at night.
Witnesses said the group was having food and drinks when the altercation broke out, leading to the shooting.
The deceased officer was identified as constable Eric Muga of Runda police station while Corporal Philip Kae who is attached to Judiciary is nursing abdomen wounds after being shot.
