The Bradley County Grand Jury is looking into the firing and then reinstatement of veteran Cleveland Police Sgt. Steve Tyson.
Cleveland City Manager Janice Casteel was among those receiving a subpoena to appear before the Grand Jury to testify.
Sgt. Tyson was rehired after the Cleveland City Council passed a motion in support of his rehiring after many family members, friends and colleagues spoke in his defense.
Lt. Tyson was terminated from his 27-year career after failing a random drug test. According to family members, Lt. Tyson suffers from kidney stones and took one of his son's pain pills one night after work.
