A recent string of robberies on BART trains took a frightening turn when dozens of juveniles swarmed an Oakland station over the weekend and commandeered a train car, forcing passengers to hand over bags and cell phones and leaving at least two with head injuries, witnesses told the transit agency.
The incident — the first of its kind in recent memory — occurred around 9:30 p.m. Saturday at Coliseum Station.

Definitely something out of the ordinary for BART.
