Trump directs ICE to expand deportations in Democratic-run cities, including Los Angeles

Several people were taken into custody Saturday afternoon during an apparent immigration raid at the Santa Fe Springs Swap Meet.

The operation unfolded around 3:30 p.m. along Alondra Boulevard, just off the 5 Freeway.

AIR7 was above the scene and captured exclusive video of federal agents on the property, taking people into custody.

Several people were at the swap meet for a Saturday night concert, which was later canceled.

"First of all, it was a little unbelievable because I've been seeing it, and it hadn't directly happened to me," said one visitor. "I don't live in this area, I live in the San Fernando Valley, so to see it firsthand was kind of shocking, but also very disheartening. My father came to this country in 1968 and works very hard. I know a lot of Latinos work really hard, it's just disheartening the amount of fear that they're creating."

One witness said the agents were asking people where they were from.

"I told them I was from the United States, and then they proceeded to walk away, and they took a picture of me with a specialized cellphone camera," he said. "I took it as a personal threat. I have an uncle who served in World War II. I have an uncle who served in Korea."

CORRECTION: A previous version of this story stated that Marines were also present during the raid, but according to the U.S. Department of Defense, there were no Title 10 forces or U.S. Marines present at the Santa Fe Springs Swap Meet, and the Department of Defense was not involved in the operation. This post has been updated to reflect that correction.

Big Boy, the iconic Los Angeles DJ, spoke with Eyewitness News during Saturday's "No Kings Day" protest in downtown and said he came out because he "wants L.A. to take care of L.A."

"People are tired, we're tired," he said. "When you start to see ICE out here and the Border Patrol, people snatching people up from jobs and schools and churches, like how can you sit at the house or how can you sit anywhere and not understand that that's wrong."

He went on to say that he understands people have "their own views on certain things but there's also a part of you just being a human."

"Whatever side you're on, you gotta look at this and say that this is ridiculous," he added.

An unlawful assembly was declared in downtown Los Angeles due to demonstrators throwing bottles, rocks and other objects at officers, the Los Angeles Police Department's Deputy Chief Emada Tingirides said.

"We started off with 20 to 30,000 participants at its peak and the protest was peaceful," Tingirides said. "Not until rocks and bottles and projectiles were being thrown at our officers did we initiate crowd control tactics in an effort to bring peace and calmness in that area and protect the children and families and protesters that were there to express the first amendment."

The dispersal order was issued just before 4 p.m. after a crowd in the 300 block of Los Angeles Street began blocking traffic.They had a position of advantage and began throwing objects at the officers.

That is when the incident commander declared an unlawful assembly. LAPD administered less lethal and the crowd began to disperse.

Tingirides said LAPD carried out crowd control tactics alongside the Los Angeles Sheriff's Department in an effort to gain compliance from the group that ignored the initial dispersal order.

An unlawful assembly was declared in downtown Los Angeles due to demonstrators throwing objects at officers, LAPD's Deputy Chief said.

There were two occasions where LAFD had to go in and render aid to individuals, but when crowds don't disperse, it makes it difficult for them to do their job, she said.

The LAPD is fully mobilized, meaning days off were canceled for officers. With their partnership with the LASD and CHP, LAPD said they have enough resources to mitigate the crowd.

When asked if the 8 p.m. curfew was working, Tingirides said yes.

"Once the mayor initiated this curfew, we have seen a decrease in burglaries and looting," she said. "In fact, we have not had one burglary or looting incident in four days since the mayor instituted the curfew in the downtown L.A. area."

Ahead of the planned curfew set to go into effect at 8 p.m., LAPD is asking all demonstrators to leave the Civic Center area in downtown.

Shortly before the request, the LAPD said officers had requested assistance due to "agitators" throwing objects at officers.

Earlier, a dispersal order had been issued for an area of downtown after the LAPD said people in the crowd were throwing rocks, bricks and bottles.
