OAKLAND — Protesters vandalized a bus carrying Facebook employes on Monday morning near the MacArthur BART station and slashed one of the vehicle’s tires, police said.

About 9:23 a.m., about six to 10 people blocked the bus on the 40th Street side of the MacArthur BART station in North Oakland as the bus was taking on passengers to take to work, police said.

No one was injured in the melee, but one of the protesters stabbed one of the vehicle’s tires. The tire was repaired a short time later.

Police said witnesses pointed out three people — two males and one female — who were reportedly involved in the protest. The reason for the protest was not known.

Police detained the trio and cited one of them on suspicion of vandalism.

The bus belongs to SFO Loop, a South San Francisco company, police said.
