Kelvin Lett—a former police misconduct investigator for the Chicago Police Department—claimed in a lawsuit filed Sunday that he was fired "after he refused to give false testimony to make a shooting by an officer seem like it was not justified," according to the Chicago Sun Times.

Lett alleges that former Police Board Member Lori Fairley—who is not named as a defendant in the case—ordered him "to alter his reports so as to lie about his findings on a particular case regarding an officer-involved shooting of a civilian."

The suit claims that Farley ordered Lett to "lie in his reports that a gun was planted on the victim by the officers involved in the shooting."

He refused to do so, saying there was no evidence to suggest that had happened.

Two weeks later, Lett was transferred to "janitorial duties" and in February 2017, Farley fired Lett.

Named in the lawsuit are the City of Chicago, the Civilian Office of Police Accountability, the Independent Police Review Authority, as well as AFSCME Local 654 and Council 31.
