In retaliation for BART's shutdown of cell phone service Thursday night at some BART stations to prevent another planned protest, protests organized by the hacker group Anonymous closed transit stations across San Francisco on Monday night.
Approaching the 5 p.m. protest time at BART's Civic Center Station, police tactical units with riot gear patrolled the platform.

Protesters in the underground BART station numbered around 50, some bearing signs. There was an equal number of members of the media in attendance to document the protest.
