A Denver firefighter, known as 'Racist Rover,' has been fired.

Lt. Jared Russo was terminated for 'hateful intolerant speech,' according to 9News.

The 12-year veteran reportedly mocked people of ethnic backgrounds and made racist jokes, the station reported.

Other firefighters didn't like working with him because of his behavior.

“Lieutenant Russo’s misconduct extended beyond a single house to where he became known throughout the district and beyond as the ‘racist rover,’ ” officials noted in a notice of disciplinary action document.
