A Chicago clothing store owner is hoping YouTube viewers will help identify a flash mob he says stole around $3,000 in designer jeans.

Luke Cho, the owner of Mildblend Supply Co. in Wicker Park, posted a surveillance video of more than a dozen teens walking into the store Saturday and stuffing their bookbags with jeans before walking out, MyFoxChicago reports.

"They came marching in and basically ransacked the place and tried to grab whatever they could,” he said.

Cho says he has dealt with a dozen shoplifting incidents since his store opened six months ago, but none as sophisticated as the “flash mob” robbery, MyFoxChicago reports.

Chicago police are investigating the incident.
