A Chicago Police officer was shot in the leg while after responding to a burglary in the Gold Coast neighborhood early Monday, according to police. A suspect was also wounded in the “exchange of gunfire.”

Shortly after 4 a.m., police were called to a store on Oak Street for an attempted smash-and-grab burglary involving several vehicles, CPD superintendent Larry Snelling told reporters. Several suspects fled as officers arrived, and police caught up with one near Walton and State streets, Snelling added.

An “exchange of gunfire” soon followed, and other CPD officers applied a tourniquet to the wounded officer before driving him to Northwestern Memorial Hospital. That officer is 55 years old and has been with CPD for 17 years, Snelling said. He was one of two officers who fired their weapon.

The wounded suspect was undergoing surgery, also at Northwestern Memorial Hospital, as of Monday morning, the superintendent added. Police are searching for other suspects involved in the smash-and-grab attempt, and the CPD detectives and the Civilian Office of Police Accountability are investigating the shooting, Snelling said.
