Arrest made in robbery aboard Oakland train

The first arrest has been made in the violent robbery of Bay Area Rapid Transit passengers by a mob of up to 60 youths on a train a week ago.

In a tweet late Friday, BART said a minor was arrested, and more warrants for other identified suspects were on the way.

The announcement was made six days after the robbery at the Coliseum station in Oakland, in which youngsters were spotted hopping over fare gates before boarding a Dublin-bound train after 9:20 p.m., then swarming passengers and robbing six of them by force. Another was robbed on the platform.

Authorities said a purse, duffel bag and five cellphones were taken during the robberies. At least two passengers were treated by paramedics for face and head injuries, police said.

After robbing passengers, police said, the juveniles ran into the surrounding neighborhoods before officers could arrive at the scene.
