Christopher Urban, 39, was arrested and charged with theft about 5 p.m. Saturday at the Northside Summerfest on Lincoln Avenue at Irving Park Road in the North Center neighborhood, police said.
How did he do it? By posing as an employee of the event company running the fest. Urban offered to relieve workers for a break, then was caught removing money from the donation box. About $658 worth of donations.
He tried to walk off with the cash, but a security guard, an off duty police officer, nabbed him before he could get away.
