A contract instructor for the academy that trains police officers in St. Louis County has been fired for using a racial slur during a class.

CLAYTON — A contract instructor for the academy that trains police officers in St. Louis County has been fired for using a racial slur during a class.

KSDK-TV reports that St. Louis County Police Chief Mary Barton fired the instructor after an investigation.

St. Louis Police County Police Association business manager Matt Crecelius said officers alerted supervisors of the comment on Oct. 20.

The instructor's name, and details about the comment, have not been released. Barton, in a memo on Wednesday, said discrimination, "whether by word or deed, shall not be tolerated by any of us."

The Ethical Society of Police, a police officers union that advocates for racial and gender equity, on Thursday called it "disturbing" that the instructor can still work with other departments and urged that the instructor's license be immediately revoked.
