Montgomery County police are investigating a robbery of a 7-Eleven in Germantown by more than two dozen people.
Police say the so-called "flash mob robbery" happened around 1:45 a.m. Saturday.
The group of about 24 people entered the store, stole snacks, drinks and other items and left after about one minute.
Police have identified several of the suspects through surveillance video.
A police spokeswoman says she doesn't know how the robbery was organized.
