A large group of juveniles robbed a clothing store in Georgetown on Tuesday evening and stole $13,000 worth of items, according to D.C. police.

The incident happened just before 6 p.m. at the Diesel store in the 3000 block of M Street NW. More than 20 people went into the store and grabbed several items off the racks, police said. They stole four leather jackets, costing about $800, and an additional $12,000 worth of merchandise.

One person who worked at the store was said to have been pushed from behind by someone in the crowd. The employee was not injured, according to police. Police described the suspects only as juveniles.

A spokesperson for Diesel did not respond to requests for comment.
