U.S. immigration officials initiated a new series of enforcement operations in the Los Angeles area on Sunday, according to sources familiar with the effort.

This latest crackdown in Southern California follows similar actions ordered by the Trump administration in cities like Chicago and New York, targeting individuals residing unlawfully in the country.

Footage shared on social media by community activists showed federal agents gathered outside a residence east of downtown Los Angeles. In the video, activists can be heard using megaphones to inform residents of their rights.

"There are ICE agents present, so do not open your door. They cannot enter without a judicial warrant signed by a judge," one activist announced through a megaphone.

The video captures approximately 20 minutes of the incident before the agents, who appear to be federal officials, depart in their vehicles.

It remains unclear how many individuals were detained as part of Sunday’s operation. has reached out to Immigration and Customs Enforcement (ICE) for further comment.

Earlier, sources informed that immigration authorities were preparing for a wave of enforcement actions in Los Angeles aimed at detaining and deporting undocumented individuals.

A member of the Community Self-Defense Coalition reported that around 150 activists were patrolling the city throughout the day.

ICE officers were reportedly assisted by other federal agencies, including the Drug Enforcement Administration (DEA), Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), the FBI, and U.S. Customs and Border Protection (CBP).

Los Angeles is among several Democratic-led cities in California, Colorado, and Illinois that have adopted sanctuary policies limiting cooperation with federal immigration enforcement efforts.

This enforcement push comes as the Los Angeles area continues to recover from the devastating Eaton and Palisades fires in January, which claimed 29 lives and destroyed thousands of structures.

Nationwide Immigration Crackdown

This latest operation marks the first major immigration enforcement action since the removal of ICE’s acting director, Caleb Vitello, amid concerns over a slowdown in arrests, according to multiple sources. The Wall Street Journal was the first to report on Vitello’s removal.

Although President Donald Trump has publicly denied dissatisfaction with deportation rates, sources say he has privately expressed frustration to his top immigration advisers.

The Trump administration ramped up immigration enforcement soon after taking office on January 20. Since then, more than 14,000 undocumented immigrants have been arrested, according to border czar Tom Homan, who made the announcement during a February 11 radio interview.

Chicago was among the first cities to see stepped-up immigration enforcement, with ICE conducting “enhanced targeted operations.” Similar actions have been reported in Atlanta, Puerto Rico, Colorado, and Austin, Texas.

Homan, who was personally involved in operations in Chicago, described them as "criminal enforcement actions."

Last Monday, Homan praised what he called a record-low number of border encounters—229 within 24 hours—but stated he would not be satisfied until every undocumented immigrant with a criminal conviction was apprehended.

"We have nearly 600,000 undocumented immigrants in the U.S. with criminal records, and I won’t be satisfied until we remove every one of them," he said in an interview with Fox News.

Despite acknowledging ICE’s efforts, Homan expressed dissatisfaction with the overall number of arrests.

"ICE is doing an outstanding job," he Dana Bash. "But I’m not happy with the numbers because we still have many criminals to track down."

Additionally, a New York City immigration operation was part of a broader effort targeting suspected gang members, a law enforcement official confirmed. Homeland Security Secretary Kristi Noem participated in the operation, later referring to the arrested individuals as "dirt bags" in several online posts.
