The Boulder Police Department is looking for a cross-dressing man wearing clown makeup who robbed a liquor store on Saturday night.Boulder police spokeswoman Sarah Huntley said officers received a call from the Boulder Beer Emporium, on the 4700 block of Table Mesa Drive, just before midnight. The caller said that the store was robbed.The witnesses described the robber as a man wearing red and white face makeup, a red and purple wig, a fake nose and a denim dress. Employees told police they didn't think anything was peculiar when he walked into the store because of the Pridefest events happening over the weekend in Denver, Huntley said.The clerk said the man walked up to an employee in the store and asked for help in a feminine voice, saying, "Will you help me? My husband is out of work."After being rebuked by the employee, the man walked to the checkout stand and showed the clerk a pistol.The man did not take any beer or liquor and left with an undisclosed amount of money, Huntley said. The robber fled on foot just as two other customers were walking into the store, Huntley said.A surveillance picture is expected to be released Tuesday.
