OAKLAND, Calif. (AP) — Dozens of teens robbed and assaulted passengers on a regional transit train in Oakland over the weekend in an apparently orchestrated attack, authorities said Monday. Witness accounts and surveillance video showed 40 to 60 teens jumping the fare gate at the Coliseum Station Saturday night, said Bay Area Rapid Transit spokeswoman Alicia Trost. They entered a train that pulled into the station, grabbed bags and cellphones from seven passengers and then ran off into the neighborhood before transit police could respond. Two people suffered minor facial injuries and were treated at the scene, Trost said. Authorities were reviewing surveillance video to try to identify the suspects and planned to share it with city police, the Oakland school district and housing authority officials. The transit system has experienced a series of robberies, prompting officials to step up patrols in recent weeks.
