About 50 people swarmed into a convenience store in Montgomery County over the weekend and made off with snacks and drinks, county police said.
The incident occurred about 11:30 p.m. Saturday at a 7-Eleven store in the 12200 block of Tech Road in the White Oak/Calverton section of the Silver Spring area, police said. Those involved included teenagers and young men and women, police said.
As part of their investigation, police said, they were trying to determine whether anyone involved was among those at a birthday party in the area. So far, no connection has been established, police said Monday night.
Police said they stopped six people in the Tech Road area after the incident. All of them had items from the store, and none of them had a receipt, police said.
Police said they identified the individuals, but made no arrests.
The value of the items taken was not immediately determined, police said.
Police said they did not believe that the incident was connected to one on Aug. 13 in which a group of people swarmed into a convenience store in Germantown, taking about $450 worth of candy, snacks and drinks.
Social media were not used to assemble groups for either incident, a county police spokeswoman said.
In another August incident characterized by what appeared to be a similar technique, about $70 worth of merchandise was taken from a convenience store in Northeast Washington after about 10 young women entered at 3:15 a.m.
In earlier swarming incidents in the District, groups of people entered clothing stores, grabbed merchandise and fled.
