Sixty people were arrested Sunday night in San Francisco following a chaotic weekend that included a solidarity protest in the Northern California city following President Donald Trump‘s deployment of 2,000 federal troops to Los Angeles to tamp down immigration protests.

In San Francisco, protests that began peacefully near an Immigration and Customs Enforcement office grew quickly into a tense standoff between demonstrators and law enforcement. Police declared the protest an unlawful assembly, and most of the protesters dispersed. Several others stayed behind, marching through the streets and causing mayhem before officers began making arrests.
