Protesters in San Francisco spent the day blocking the entrance to an unmarked building in the South of Market area. Immigrants had been told to report there in what some believed was a trap by U.S. Immigration and Customs Enforcement to capture people for deportation.

Organizers say at least a dozen immigrants received text messages on Friday, ordering them to check in with federal immigration authorities over the weekend.

Protesters filled the streets on Saturday, marching at noon from Dolores Park to the Civic Center as part of the nationwide No Kings protests. Thousands of protests were organized across all 50 states as a rejection of President Donald Trumps agenda.

Hundreds marched again in San Francisco to protest the ongoing ICE raids in California, the second day of largely peaceful protests marred by incidents of violence and arrests.

Demonstrators who hoped to show peaceful support for immigrant rights protesters in Los Angeles wound up clashing with the police.

The outburst of public dissent occurred over the weekend after ICE began raids across Los Angeles. ICE said on Saturday that its “operations in LA this week” had resulted in 118 arrests of immigrants in Southern California.

More than 150 were arrested at immigration enforcement protests in San Francisco's Financial District Sunday evening, with police officers injured and significant property damage left behind, authorities said.

Journalists and advocates say San Francisco police detained multiple reporters and interfered with First Amendment rights during recent protests against immigration raids.
