The county boss reportedly arrived at around 10am with the grilling going on until past 5 pm in the evening according to EACC sources.

According to the Standard, Waititu was asked to report to make some clarifications about Sh588 million tender which companies associated with his family are said to have benefited.

“Preliminary investigations show the contractors paid monies to senior county officials, their companies or relatives through proxies,” said Twalib Mbarak, the EACC boss.

The letter dated June 7 was signed by Mr John Lolkoloi, the deputy director in-charge of Forensic Investigations, on behalf of Mbarak.

“The commission is investigating allegations of corrupt practices at the county government of Kiambu in disbursement of funds during the 2016/2017, 2017/2018 and 2018/2019 financial years. To facilitate our investigations, kindly avail the following members for interview and statement recording," read part of the letter.

Some of those summoned included Kigo Njenga (Finance), Karungo Thangw’a (Youth), Wilson Mburu (Roads), David Kuria (Environment), James Maina (Lands), Mary Kamau (Health), Joseph Ng’ang’a (Education), Joseph Kamau (Agriculture) and Margaret Ruinge (Administration).

Over time, Waititu has accused detectives of being used by political operatives to frustrate him due to his ties with Deputy President William Ruto.

Last week, Waititu was booed at Githurai in presence of Dr Ruto. However, he has defiantly maintained that he will continue backing Ruto.
