Chicago federal intervention: Tracking surge in immigration enforcement operations | Live updates

Federal agents arrested three people after a crash during a north suburban immigration operation on Friday, officials confirmed.

Neighbors say the terrifying moments unfolded earlier in the day at Evanston's intersection of Asbury and Oakton, just a few blocks from an elementary school. On Friday night, the Trump administration confirmed that three U.S. citizens were arrested.

Witnesses say a man and a woman in a red car were following the agents to warn people of their presence. That's when, the witnesses said, the agents slammed on their brakes just past the intersection, causing the people in the car following them to crash into them.

Neighbors say the agents then violently pulled the man and woman out of their car, and when members of a neighborhood watch patrol came to see what happened, one agent allegedly pulled a gun on one of the bystanders and threatened to pepper-spray him.

Evanston Fire Department paramedics responded to provide medical care for those exposed to pepper spray, Evanston police said in a statement.

Late Friday night, the Department of Homeland Security accused people who watched the incident happen of being "aggressive," saying in part, "As agents tried to make a U-turn, the red car crashed into Border Patrol. A hostile crowd surrounded agents and their vehicle, and began verbally abusing them and spitting on them."

Witnesses say the agents threw both the man and the woman into their vehicle and drove away. It is unclear where they were taken, and ABC7 blurred their faces, because we do not know if they have been charged with any crimes. Click here for more.

A Ring doorbell camera captured an immigration arrest in Arlington Heights Thursday.

Federal agents got out of a van and placed landscaper Miriel Medina into custody.

A US Postal Service worker was pushed to the ground trying to intervene in an Arlington Heights immigration arrest of a landscaper, video shows.

He did not resist the arrest.

But when a nearby postal worker tried to step in, agents pushed the postal carrier to the ground.

Medina's daughter said her father is living in the U.S. without legal permission.

Medina is being held at the Broadview U.S. Immigration and Customs Enforcement facility, but hasn't been processed yet.

Neither the Department of Homeland Security nor Border Patrol immediately responded to requests for comment on Medina's arrest.

Medina's court date is set for Nov. 12.

Cellphone video captured a man being taken away by federal agents near Waveland and Kimball in Irving Park on Friday morning. The man was put in the back of a truck, and then, agents drove away.

Noem said immigration enforcement will not be paused during Halloween weekend. On Friday, that was evident.

Over at Sawyer and Lawrence in Albany Park, a chaotic scene played out.

Surveillance video from a neighboring business shows agents arriving. A crowd then gathered as two people were detained.

Cellphone video shows agents telling people they were assaulted. Video also shows agents attempting to pull someone out of a vehicle.

Olivia Dunn says her neighbor was among the people detained.

"We could see that they were detaining someone and throwing them down on the ground. It happens to be our friend," Dunn said. "They warned us that there would be tear gas, and then, they deployed pepper bullets."

The incident took place a short distance from the office of 33rd Ward Ald. Rossana Rodriguez-Sanchez, who came out to see what happened. At one point, agents were seen pushing the alderwoman.

"I think they decided to come with a vengeance, because they were asked to slow it down so the kids could have a joyful time. They decided to escalate it," Rodriguez-Sanchez said.

ABC7 reached out to Customs and Border Patrol for comment but did not immediately hear back. Click here for more.

After weeks of verbally condemning the aggressive federal immigration crackdown in the Chicago region, Illinois lawmakers approved legislation banning civil immigration arrests in and around state courthouses early Friday morning.

House Bill 1312, among other provisions, would also allow Illinois residents to sue immigration agents who violate their constitutional right to due process and protection against unreasonable searches and seizures.

It heads to Democratic Gov. JB Pritzker's desk after clearing the Illinois Senate 40-18 and the Illinois House 75-32 in the waning hours of their annual fall veto session.
