FROM FOX NEWS: A mob of up to 20 anti-ICE protesters swarmed and attacked immigration agents outside a San Francisco courthouse on Wednesday, with one keffiyeh-clad agitator allegedly armed with a knife threatening to stab an officer and go after his family, officials said.
Adrian Guerrero, a U.S. citizen, slashed the tire of a government vehicle during the clash at the immigration courthouse on 100 Montgomery Street, according to the Department of Homeland Security (DHS).
The incident unfolded as ICE agents carried out a removal operation, when protesters surrounded them and physically assaulted four officers, throwing punches and deploying pepper spray.
Guerrero repeatedly launched threats, saying, “I’m going to f— you up,” “I’m going to go after your family,” and “I’m going to stab you,” according to DHS, citing court filings.
In a post on X, DHS shared additional details about the attack:
On August 20, ICE agents were conducting targeted immigration enforcement at 100 Montgomery Street in San Francisco, CA. As law enforcement attempted to carry out its sworn duties, anti-ICE rioters surrounded and assaulted four federal agents outside the building. The agents sustained injuries from pepper spray deployed by rioters.
One individual, Adrian Guerrero—a U.S. citizen—was charged with assaults and destruction of federal property. According to court filings, Guerrero slashed the tire of a government vehicle and threatened to stab a law enforcement officer.
Our brave ICE law enforcement are facing a 1000% increase in assaults against them as they risk their lives to arrest the worst of the worst criminal illegal aliens. These acts of violence are fueled by sanctuary politicians’ rhetoric vilifying our law enforcement.
