Three offenders, each armed with their own handgun, approached the off-duty cop and a second victim around 9:25PM in the 3100 block of N. Ravenswood.
The gunmen took the cop’s .38-caliber handgun and took wallets from both victims, but they dropped the officer’s police star nearby, a source said.
All of the robbers climbed into a dark-colored SUV that was last seen heading west on Belmont.
The off-duty cop described the offenders as three black males in their teens or early 20’s. Each of them was armed with a semi-automatic handgun and was wearing dark clothing and a hoodie, the officer said.
