Directorate of Criminal Investigation detectives are searching for Nairobi County Assembly Clerk Jacob Ngwele after Director of Public Prosecutions Noordin Haji ordered his arrest.
Mr Haji also ordered the arrest of four other senior county officials over the irregular awarding of a tender.
On Friday, Mr Ngwele escaped a DCI dragnet at the assembly, where three of his colleagues were arrested.
The whereabouts of the clerk are not known and his phone has been off since then.
Five staff and a proprietor have been accused of defrauding the county through unscrupulous tendering.
Those apprehended on Friday are Deputy Clerk Adah Awuor Onyango, senior procurement officer James Kariuki Kaguma and senior finance and planning officer Fredrick Macharia Mwangi.
To which Ms Elachi retorted: “Don’t raise your voice at me. We shall give you time to defend yourself. You should not raise your voice at me.”
The confrontation led to the suspension of the two by the County Assembly Service Board the same month to pave way for investigations.
The Board consists of the Speaker, the Clerk, majority and minority leaders and a member of the public.
