A protest organized by the hacker activist collective "Anonymous," intended to draw attention to issues with the Bay Area Rapid Transit (BART) police, turned chaotic and violent last night, resulting in almost half of the demonstrators being arrested.
Protesters did manage to temporarily shut down two BART stations and snarl traffic for a couple hours, but once darkness fell the trouble began.
Area reports place some of the demonstrators breaking off into splinter groups as they marched, running down side streets, tossing trash cans, throwing stink bombs at police and kicking the glass out of bus stop shelters. One person was also arrested on suspicion of "lighting a flammable substance."
The crowd was about 100 people, and authorities initially estimated that 40 were arrested. The protesters were outnumbered by the gathering of police and journalists there to observe the demonstration, according to PC Magazine.
