DC Police are investigating what's being called a "flash mob robbery" at a Dupont Circle clothing store.
Police say on Monday, 20 or so teenagers entered the G-Star Raw store on Connecticut, grabbed clothes and ran out of the store with approximately $20,000 in merchandise.
Other media outlets have reported on similar incidents in the past.
Just two weeks ago, Georgetown Tee's was hit by a flash mob that took thousands of dollars worth of merchandise.
In 2009, a flash mob rushed into Universal Gear on 13th Street Northwest, ripped clothes off the racks and walls, and ran out of the store.
