Treasury Principal Secretary Dr. Kamau Thugge has been left off the hook in joint corruption charges with his former boss Henry Rotich, after the government moved to withdraw his case and use him as a witness.

The Director of Public Prosecutions Noordin Haji has asked the court to withdraw charges against the PS in the Arror-Kimwarer dam scandal since he will now serve as a witness against his former boss.

The duo had been charged with conspiracy to commit an economic crime, abuse of office, financial misconduct and failing to comply with rules and regulations relating to management of public finances.
