In a statement released early Friday, EACC said the Director of Public Prosecution Noordin Haji approved the arrest of the suspects after a series of investigations linked them to corruption and misconduct in office.
Three former Kitui County officials were Friday charged in a Machakos court with irregular and fraudulent awarding of tenders.
But the suspects, who were arrested by detectives from the Ethics and Anti-Corruption Commission (EACC), did not take a plea.
Chief Magistrate Alfred Kibiru of the Machakos Anti-Corruption Court ruled that his court does not have jurisdiction to hear the case.
He directed that the plea be taken in a Kitui court.
Mr Kibiru also said that bond hearing should be done in a Kitui court.
Lawyer Moses Kimuli, who represented the suspects, argued that the case should have been prosecuted in Kitui.
