The Directorate of Criminal Investigations (DCI) is searching for a man who invaded the Bondo Police Station armed with crude weapons, including stones, catapults, slings, petrol bombs, and other concealed weapons.
The man, whose identity is yet to be determined, is believed to have carried out the deadly act with Sostine Otieno, who is already in police custody.
He was captured in a phone recording attacking a police officer and leaving him sprawled on the tarmac.
He then proceeded to rob the officer of his anti-riot gun, which was later recovered.
Meanwhile, one of the officers, whose life was saved by a Good Samaritan, is admitted in critical condition at Bondo Hospital.
