One (or More) Less Pure Girls?

Tonight leaving Sanlitun after a shopping trip to 3.3 (its amazing how quickly shops close down and open up there), I came across a massive law enforcement presence (城管执法) outside one of the Pure Girls, while all the others were closed down. Finally busted for selling fake alcohol? Something more sinister? If anybody knows, I'd love comments, in the meantime, I'll be watching Beijing Boyce even closer than usual, as he knows everything that happens around town.
