Homes in high-end Runda and Garden Estate area belonging to Kiambu Governor were as early as 6 a.m. raided on Thursday.
The Ethics and Anti-Corruption Commission (EACC) officers are yet to confirm what the raid was all about.
The governor has however been on the spot recently over the allocation of funds in his county.
On May 2 this year, questions arose over the Kiambu County Government’s alleged allocation of Ksh.1 billion to functions of the national government.
The Auditor General revealed that the county had budgeted for State House functions, benefits for retired presidents, Free Primary Education and the South Sudan peace program.
In his defence, Waititu insinuated that the report might have been interfered with to embarrass him.
“I want to believe that this report was not interfered with by anybody to put in those things so that when I come here I will be cornered the way you’re cornering me,” said Waititu.
In a separate case that was presented to Justice James Makau on May 8, the Kiambu County Government admitted to not following proper procedure in making a supplementary budget seeking Ksh.16.5 billion for the current financial year.
Mr Waititu has also been questioned over his recent property acquisitions, including that of a building located within Nairobi’s central business district.
But in videos posted online by his supporters, Mr Waititu claims the investigations are politically influenced.
He says he has worked hard to acquire his property.
