Inspector General of police Hillary Mutyambai and Director of Criminal investigations(DCI) boss George Kinoti have resigned.
Kinoti has served at the helm of the criminal investigating agency since 2018.
Mutyambai's resignation comes a month after he took medical leave on August 26, 2022.
In a press release, the police boss indicated that Mr Noor Gabow, the Deputy Inspector General - Administration Police Service will act in his place during his absence.
"This is to inform the general public that I will be away from the office attending to a
medical checkup effective today, 26th August 2022.
"In my absence, Mr Noor Gabow, the Deputy Inspector General - Administration
Police Service will act as the Inspector General of the National Police Service until
my return," the press release read.
Previously before the general election was conducted, President William Ruto had expressed concerns about Mutyambai terming him as incompetent.
Ruto spoke after his meeting with delegates from the International Republic Institute (IRI) and National Democratic Institute (NDI) on the pre-election assessment mission ahead of the August 9 polls.
At the time he said while he has faith in the police unit to do their job during the general election, his fears rested with their boss.
"The only concern from where we sit is the police. We do not doubt the capacity of the police to handle the situation, we doubt the command. We have the most incompetent IG in the whole world and that's the problem," DP Ruto claimed.
He questioned Mutyambai's office's ability to handle a crisis independently and, in a familiar pivot made reference to his relations with President Uhuru Kenyatta.
Ruto said he believes the IG is in touch with the President and could be at variance with the people deemed as his opposers.
He alleged the office of the IG had been overtaken by the president making it a rival in the August 9 election.
"His incompetence doesn't play out when things are working but when there is a decision-making issue. He cannot make a decision as he lacks the capacity. The command is done by others. His office is not independent," he added.
