California authorities arrested 25 demonstrators after they briefly stopped traffic on San Francisco’s Bay Bridge on Monday as a part of protest tied to the Martin Luther King Jr. holiday. Members of the protest group Black.Seed, an offshoot of the Black Lives Matter movement, chained themselves and their cars together to form a line across the bridge in protest of police brutality. All lanes heading into San Francisco were shut down for about 30 minutes before California Highway Patrol arrived. Authorities began arresting activists and moving cars to the side of the road. Protesters had initially planned to remain chained to the bridge for 96 minutes to symbolize the 96 hours of direct action protests that happened over the weekend in Oakland.
