Chicago federal intervention: Tracking surge in immigration enforcement operations | Updates

Department of Homeland Security Secretary Kristi Noem apparently chose Mexican Independence Day to send a message to the immigrant community, arriving in force on Tuesday morning to an Elgin home and taking four people into custody.

They arrived like a military operation. Agents could be seen in camouflage uniforms with military helicopters circling above at about 5:30 a.m. They broke the front door down and entered the home. Members of Elgin's rapid response teams want to keep their identities anonymous.

"It's terrorizing everyone, putting people back into hiding. People don't know what to do," one team member said.

Noem was apparently on hand and posted footage of Immigration and Customs Enforcement agents taking occupants of the home into custody, saying they were violent criminals wanted for crimes like assault and DUI.

The only problem is two of the four people they arrested are apparently U.S. citizens who they released shortly afterward. One of them is a man named Joe, who preferred not to speak on camera.

"I'm just glad I had my wallet, my ID, and I cooperated," Joe said.

That operation was one of several ICE arrests made in the area on Tuesday. A short time later, ICE agents stopped a driver on Route 31, a few blocks away, taking him into custody.

ICE agents arrested another man in the Little Village area a short time after video appeared to capture an arrest at 24th and Albany on Monday.

Just a few few blocks away, agents stopped a Venezuelan man, taking him into custody, as well. Noemi Rivera witnessed it all as they brought him to the car in handcuffs.

In Spanish, Rivera said, "I got very scared and nervous because I saw everything and I shot the video."

A distraught Venezuelan mother and her two small children sat on the steps on a Little Village building moments after, she says, ICE detained her husband while they were in their car at 24th and Albany on Monday morning.

Video she recorded inside the car shows an ICE agent telling the couple that they need to open the door. The woman replies not to open the door because they are legal.

An ICE arrest in Little Village, Chicago happened at 24th and Albany just one day after the neighborhood's Mexican Independence Day parade.

The woman shared the video with the Little Village Community Council, and Anita Clara witnessed the exchange from the sidewalk.

Clara says the agents told the man to get out of the car, and when he did not, they started hitting the car. Then, he got out of the car, and the wife and kids were crying.

"He was telling them, 'I'm legal. I have my legal status.' But they didn't care. They took him with them, left no information for the mom," said Little Village Community Council President Baltazar Enriquez.

Robert Centeno saw the law enforcement vehicles rush away, leaving the mother and her children in a white car in the middle of the intersection. Centeno stopped to help her.

"As I got close, I see the passenger crying, a female, two kids, crying, too," Centeno said. "They had already blocked the back and front part. She said they started hitting the car, like they were going to damage it. The kids were crying, so he just got out."

Centeno says the mother told him that the agents did not present a warrant. She says her husband has a work visa and no criminal record.
