A flash mob of teenagers robbed merchandise from a Diesel store in upscale Georgetown in Washington, D.C., Tuesday.

Around 20 to 30 juvenile suspects entered the store during the 2flashmob event on Nov. 24 and started taking items off the racks. Reports say they stole an estimated $13,000 worth of designer clothing, including four leather jackets that cost $800 each, according to The Washington Post.

The robbery happened just a month after retailers had to stop using "Operation GroupMe" - a social network program that allows shop owners to communicate with each other and the police whenever they suspect potential shoplifters in the area. The community of retailers were scrutinized for allegedly using the app to racially profile people, allegedly getting more suspicious of black shoppers than the rest, according to New York Daily News.

No injuries were reported, and no arrests had been made as of Thursday, according to The Washington Times.

A similar incident in Georgetown occurred in 2014. That time, the shop victimized by the flash mob daytime robber was the now-closed True Religion store on M Street, according to International Business Times.

Diesel has not commented on the incident.
