University Council says Mr Spencer Sankale Ololchike will be paid one month's salary in lieu of notice.
His sacking comes nearly two years after the Mara Heist exposé aired on Citizen TV on September 1, 2019.
The Maasai Mara University whistleblower who exposed a graft scheme dubbed 'Mara Heist' has been sacked on grounds of sustained insolence to his employer, libel, defamation and disregard of university standards and procedure.
The University Council said it found that Mr Spencer Sankale Ololchike, who was the institution's chief finance officer, had committed nine offences among them incitement of staff and the general public against the university, gross insubordination and failure to act in its best interest.
