MONTEBELLO, Calif. — A wave of immigration raids swept through Southern California on Wednesday, leaving both workers and local residents on high alert.

According to civil rights organizations, U.S. Immigration and Customs Enforcement conducted at least 20 operations spanning from East Los Angeles to the downtown area, including a notable incident in Montebello that was caught on surveillance cameras.

The footage from Montebello reveals an unmarked truck arriving at the scene, with ICE agents quickly emerging to encircle a residence. In an instant, one agent ascends a ladder to the roof, prompting construction workers stationed there to flee by leaping from one rooftop to another in a bid to escape. Fortunately, no arrests were made.

“They were genuinely terrified, fearing for their lives and uncertain of the unfolding events,” explained Manny, the contractor responsible for employing the workers.

Upon hearing about the incident, Manny hurried to the site, discovering his team visibly shaken and anxious.

“We just gathered and I prayed for all of them, and I prayed for their protection and that God would give us peace during this troubled time,” he said.

Manny said this doesn’t just affect the people ICE targets – it affects everyone trying to work and survive.

“Some people are scared to come back to work,” he said. “They’re just a little (shaken up) and they just don’t want to experience that again.”

Civil rights groups said Wednesday’s operation in Montebello was one of many taking place throughout the region.

Videos from Little Tokyo in downtown L.A., Commerce and Pico Rivera showed agents confronting and detaining people in public areas.

“They’re using brutal violence against an unarmed, civilian population to impose their political will,” said Ron Gochez of Union del Barrio. “Things are escalating and so for us, we know we have to continue our work, we have to continue organizing, we have to continue defending our community.”

Gochez pointed to a new California law requiring ICE agents not to wear face coverings, but he said it’s not being enforced.

“They don’t have to abide by state law or local ordinance, and so to pass these meaningless bills into law here in California when these are federal agents who don’t have to listen to them, it’s really a waste of our time,” he said.

Meanwhile, in cities like Montebello, neighbors said they’re thinking twice before leaving their homes.
