Police say a man entered the store, located in the 4400 block of Broadway, at high noon and produced a black handgun. A female worker fled out the back door and called 911.
Video cameras in the area captured images of the man fleeing into a nearby alley with several phones. There, he changed into a construction vest and hard hat before continuing northbound.
He is described as a black man in his 20’s or 30’s, a little over 6-feet tall, with a very short haircut.
Previously, the "construction crew" wore vests, helmets, and painter-type breathing masks during the actual robberies:
• A pair of men dressed as construction workers robbed a T-Mobile store at Damen and Irving Park road on May 31.
• On June 6, a similarly-dressed duo held up another T-Mobile store in the 1900 block of Harlem, on the border of Chicago and Elmwood Park.
