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.

Protesters outside the San Francisco ICE headquarters were in a long standoff with dozens of riot police. Officers then rushed the crowd.

Protests erupted nationwide, including in San Francisco, Chicago and NYC, after tensions escalated in LA over immigration raids. See the photos.
