CHICAGO — A retired Chicago police officer is in serious condition after being shot while attempting to foil a robbery on the city’s South Side Thursday morning.

The shooting happened around 7:30 a.m. at 71st Street and Wentworth Avenue, just outside a Currency exchange.

According to police, a 58 year-old woman was outside, opening the door to the Currency Exchange business when a car approached her and two men exited the car and attempted to rob her.

A 60-year-old retired police officer intervened. Police said there was an exchange of gunfire, and the man was shot multiple times.

The man was transported to the University of Chicago Medical Center where he’s listed in serious condition. The woman was not injured. It is unclear if any other people were shot during the incident.

During a news briefing Thursday, authorities said the retired officer’s actions were heroic.

“Even as a retired officer, he did his best, he did his job and he saved a person’s life,” said CPD Deputy Chief Fred Melean.

Police are investigating. Any witnesses are urged to call Chicago police.
