A Hispanic male in his mid-to-late 20s held up an Oak Lawn Walgreens store in around 9:15 p.m. Saturday, Oak Lawn Police said. The robber is said to have displayed a yellow and black handgun tucked in his waistband and fleeing the store with an unknown amount of cash. Police are searching for a male Hispanic, 25-29 years old, weighing 160 pounds and standing five-feet-seven-inches tall. He was wearing a Chicago Bears baseball cap, gray sweatshirt and black basketball shorts. After getting the cash, the suspect fled on foot northbound, possibly to the northwest corner of the Walgreens parking lot to an awaiting gray car driven by an unknown accomplice, police said. Mayor Sandra Bury was shopping at the 24/7 Walgreens store presumably at the moment it was being robbed. Bury said the store was full of customers. "I was shopping away and didn't know what was going on, thank God," the mayor said. "They were unrolling the police tape when I went to check out [at the registers]." Police remained on the scene. The store was still open to customers, but the main cash register area was cordoned off by police tape. Walgreens employees were ringing up customers' merchandise in the photo department. Patch will continue to follow and update this story.
