Two Chicago police exchanged gunfire with a person in Little Village Saturday night, but no injuries were reported.

The officers had stopped two males around 10:50 p.m. in the 2200 block of South Sacramento Avenue. Both had handguns, and the officers took them into custody, Chicago police said.

During the arrest, two other males were standing at the end of an alley near the officers and one of them began shooting at police. The officers fired back, police said. No one was hit by gunfire and no injuries were reported.

Police arrested the other two males after a short pursuit. A handgun was recovered, police said.

No suspects’ ages were released.

The Civilian Office of Police Accountability, which investigates whenever an officer opens gunfire, is reviewing the shooting.

The officers involved in the shooting will be placed on routine administrative duties for 30 days.
