Tuimur will be replaced by the director of personnel at police headquarters Charlton Mureithi.
The Chief Firearms Licensing Officer Levin Mwandi has been named the new PPO for Rift Valley to replace John M’mbijiwe who was interdicted on Tuesday over the saga involving a police imposter.
Nyanza deputy PPO Larry Kyeng was also promoted and sent to replace Munyambu in Central Province.
The changes announced late on Tuesday by the commission indicated Deputy Central PPO Zachary Tum has been sent to Nyanza in the same capacity.
David Baya takes over as the new Chief Firearms Licensing Officer, replacing Mwandi.
Anti Stock Theft deputy commandant Solomon Makau takes over from Michael Remi Ngugi who was also suspended over the controversy surrounding the imposter.
Esau Ochokorodi has been promoted and named Njoro OCPD, taking over from Njeru Nthiga who was suspended alongside M’mbijiwe and Ngugi.
The commission said the changes were necessitated by the interdictions announced earlier on Tuesday over the controversy surrounding a man who impersonated a senior police officer for five years.
“We have interdicted the officers with immediate effect to allow for thorough and conclusive investigations into the matter,” the commission’s chairman Johnston Kavuludi said at an earlier press conference.
Joshua Waiganjo who is accused of masquerading as a Senior Superintendent of Police since October 2002 “was allegedly deployed in the Nakuru Anti Stock Theft Unit Headquarters as the Deputy Commandant,” Kavuludi explained.
The man is already facing robbery and impersonation charges in court following his arrest last week.
