I’d like to know when the last time was that 40 to 60 youths took over a BART train car.

They usually take over non-moving department and convenience stores.

San Leandro: Police task force forms to address teen ‘wilding’

From the article (2014):

The move comes after attacks in San Leandro, where large groups of teens allegedly attacked and robbed people in recent days at Bayfair Center and near a BART station.

San Leandro police, the Alameda County Sheriff’s Office and BART police will meet Friday to coordinate a response in the event there’s more violence this weekend, said San Leandro police Lt. Robert McManus, who will lead a task force grappling with nearly 20 similar robberies. Law enforcement agencies involved will include Berkeley, Oakland, Newark, Hayward and Union City.

The robberies and attacks can be described as “wildings,” McManus said.

“It may not all be the same group but it is the same type of activity, where it’s unruly groups of teens that are primarily traveling by BART train and coming out to intimidate and commit crimes of opportunity and are attacking the victims in packs,” McManus said. “A task force is being created. We’ve reached out to all law enforcement agencies that have a BART line.”
