The National Police Service Commission has suspended three senior police officers including Rift Valley Provincial Police Chief John M'mbijiwe over the controversy surrounding a man who has been posing as a senior police officer in the region.
Others sent home to pave way for investigations against the alleged imposter, Joshua Waiganjo, are the Head of the Anti Stock Theft Unit Remi Ngugi and Njoro divisional police chief Njeru Nthiga.
The chairman of the commission Johnston Kavuludi says they have already appointed officers to take over from those suspended.
"M'mbijiwe has been replaced with Levin Mwanthi. Ngugi has been replaced by his deputy Solomon Makau and Nthiga's replacement is Esau Okadie Ochorokodi."
At a press conference on Tuesday morning, Kavuludi announced that a thorough audit of the entire police force will be undertaken within 30 days.
The investigation team which will include the Inspector General of Police David Kimaiyo has representatives from the National Police Service Commission, Attorney General chambers and the office of the Director of Public Prosecutions.
The suspended officers are among individuals named in a confidential investigation report on the Baragoi ambush that left at least 42 police officers killed two months ago.
"He [Waiganjo] was one of those people who accompanied the PPO to Baragoi but that particular day the incident had not occurred. So definitely we cannot conclusively say he was involved," Kimaiyo said.
