A Chicago police officer was wounded and a 26-year-old man was killed in an exchange of gunfire during a traffic stop, police said.

The wounded officer was shot in the wrist Thursday evening and hospitalized in good condition, while four other officers who weren’t shot were hospitalized for observation, police said.

The man who fired shots suffered multiple gunshot wounds and was pronounced dead at a hospital about a half-hour after the shooting, police said. The Cook County Medical Examiner’s office identified the man as Dexter Reed, 26.
