Pedal Pub-ers beware – there’s a mob on the loose.

The Pedal Pub, a bicycle bar powered by up to a dozen people, was attacked by a flash mob of 25 to 30 youths Saturday night as it cruised down Nicollet Mall near South Sixth Street, the Star Tribune reported.

At around 9:15 p.m. the kids jumped on the Pub, shook it and grabbed at belongings, leaving passengers alarmed, but uninjured.

The only thing stolen was a Blackberry, and the attack ended as quickly and suddenly as it had started when the kids ran off. Police responded quickly according to reports, but it isn’t clear if anyone had been arrested in connection to the attack.
