2 attempt to rob Chicago police officer outside South Side CAPS meeting

CHICAGO (WLS) -- Two people are wanted for attempting to rob a Chicago police officer on the South Side Wednesday night, police said.

The on-duty officer was sitting inside a non-CPD vehicle outside a scheduled CAPS meeting in the 2900-block of South Vernon Parkway at about 6:26 p.m. when police said two people approached in a black pick-up truck.

The passenger in the pick-up truck got out, took out a weapon and announced a robbery, but the suspects fled when they realized they were trying to rob a police officer, who was wearing civilian clothes.

No one was injured. No one is in custody and Area Central detectives are investigating.
