A Chicago Police officer claims he faced retaliation in the department after reporting other officers’ misconduct.

In a lawsuit filed Tuesday in Cook County Circuit Court, Officer Jaeho Jung says he went to a sergeant in early 2015 about an officer who made false police reports, and another who refused to fire her weapon “when required to do so, in order to protect fellow officers.”

The sergeant told the 10-year veteran that by reporting the misconduct, he now had a “brick” over him, implying Jung was “tarnished in the eyes of superior officers” and that it made him “a target for retaliation,” the suit alleges.

As a result, Jung claims, he was removed from a police tactical team, and his paid time off was cut short. He also claims colleagues used racial slurs against him.

The suit was filed against the City of Chicago and also names two officers, three sergeants and a lieutenant as defendants. A city law department spokesman said the suit had not yet been served and declined to comment Wednesday night.

The two-count whistleblower suit seeks an unspecified amount in damages.
