Possible Flash Mob Hits Maryland 7-Eleven, Police Say

A pack of 30 teens helped themselves to items in a Maryland 7-Eleven early Sunday morning in what authorities have labeled another instance of a possible flash mob. The store, which is located in Germantown, Md., was empty at 2 a.m. Sunday morning when a group of teenagers calmly walked in and picked out items as though they were shopping. Then, just as calmly as they entered the store, police say, they exited without paying for the items.
