The Ethics and Anti-Corruption Commission (EACC) has now gone after Nairobi Governor Evans Kidero and three others over allegations of graft.
The body is accusing the Nairobi boss of irregularly amassing wealth during his tenure in charge of the County.
Among the allegations against Kidero is moving of money public funds to other accounts registered in the name of proxies and his associates.
The governor is said to have transferred Sh192.5 Million from the county government to other accounts linked to his close associates including his brother.
According to a report quoted by the Nation, for instance, Sh109 Million was moved to a company whose directors are relatives of Kidero's former chief of staff Mr George Wainaina.
EACC further indicates that part of the money was later wired into the Governor's private account.
The body has also accused him of depositing Sh13.8 million to a firm identified as Gem Apartments Ltd which EACC claims is owned by Kidero and his wife.
In the same report, the anti-graft body is investigating Sh592.3 Million which is said to have been wired into one of Kidero's accounts between 2010 and 2015.
Also between January and August 2015, he allegedly received Sh32.8 million into another bank account whose source the EACC is probing.
The Commission's report has also implicated Murang'a Governor Mwangi wa Iria and his Migori counterpart Okoth Obado for allegedly taking bribes during their tenure in office.
They are accused of receiving millions from different companies to influence the award of lucrative county government tenders.
EACC is now seeking to have assets of the three governors, who are all seeking re-election, as well their associates frozen.
