The director of accounting services, his deputy and three accountants also tendered their resignation letters on Tuesday after another acrimonious falling-out with the governor over his meddling in, among other things, payment of pending bills.
The resignations came a day after county enforcement officers raided the Finance department in Thika on Monday evening and forcibly changed door locks.
Shortly after, Ms Harrison was moved to the low-profile Trade docket.
Mr Waititu immediately replaced her with Public Administration Chief Officer Wilson Kinyanjui, who was in charge of the controversial drunkards rehabilitation programme dubbed Kaa Sober, which is currently under investigations by detectives from the Ethics and Anti-Corruption Commission (EACC) over possible theft of millions of shillings.
The governor also appointed Ms Ann Muchai as the director of Accounting Services while Ms Eda Kabuithia will be in charge of the treasury, even as it emerged that their predecessors have already secured a return to the national government where they were seconded from.
When contacted Wednesday, Ms Harrison confirmed her resignation together with those of her fellow officials, but declined to give the reasons, only saying that she had left the county job for good.
But according to reliable sources within the executive including some chief officers who spoke in confidence, they angered the governor by refusing to pay pending bills to some companies, allegedly belonging to his cronies, including some ward reps.
