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.

Multiple people were detained by U.S. Immigration and Customs Enforcement agents in downtown San Francisco on Tuesday morning, merely 12 hours after thousands of protesters took to the streets in the Mission to rally against the widespread raids taking place across California.

Mayor Daniel Lurie, who won on a promise to get tough on crime, is being put to the test in the liberal city—where late-night unrest marred largely peaceful protests.

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 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.

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.

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.

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