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.

Protesters were back at a building in San Francisco's South of Market neighborhood on Sunday, where people who were working on their immigration status received a notice to report in person.

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

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.

The protest remained overwhelmingly peaceful, with music filling the air as people marched and danced down Dolores and Market streets.

SAN JOSE — Hundreds of people gathered Monday evening in San Jose, Oakland and San Francisco to protest deportation efforts by U.S. Immigration and Customs Enforcement, as well as to stand in solidarity with protesters 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.

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.

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