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

On Tuesday, the I-Team was in court, where we heard shocking testimony about unsanitary and squalid conditions alleged inside the Broadview Immigration and Customs Enforcement processing facility.

Lawyers asked a federal judge for an emergency restraining order to improve conditions for detainees.

The question on Tuesday was, what happens inside the walls of the Broadway immigration detention center where attorneys, politicians and protesters have been turned away? The stories from court are shocking and jarring.

The I-Team heard testimony from detainees estimating 150 to 170 people packed into cells at Broadview. The single-occupancy cells hold as many as seven people. People have allegedly been on top of each other and staying an arm's length away from a toilet in the shared cell.

Two men who were arrested by ICE and are now suing the federal government over these reportedly "abusive and cruel" conditions inside the facility took the stand as witnesses on Tuesday morning. They are both immigrants from Mexico who have lived in the U.S. for over 30 years.

One witness broke down in tears on the stand while describing the unsanitary conditions inside. The alleged deplorable conditions and testimony were so disturbing that the judge compared conditions at Broadview to those of a concentration camp. Click here for more.

Federal agents gathered outside of a Prospect Heights apartment complex just before 10 a.m. Monday.

As the agents dressed in uniform walked on the property, numerous residents blew whistles and recorded video on their phones.

It is unclear who they were possibly looking for, but a few minutes after 10 a.m., they took a man into custody. Friends said he does not live there but was stopping by to give a coworker a ride to work.

One woman, who wants only her first name, Adriana, used, was recording from her balcony.

"They don't care if you're a citizen or not. They just grab whoever they want to grab," Adriana said.

Relatives of a man who they allege was hurt while being arrested by Border Patrol agents say they were blocked from seeing him in the hospital.

The arrest happened over the weekend.

Video shows Ricardo Aguayo Rodriguez wrestling with federal agents.

His family says he suffered serious head and face injuries.

He has since been released from the hospital and remains in federal custody.

A spokesperson for Gottleib Hospital said they were following protocol. In a statement, they said, "When law enforcement personnel come to our hospitals to seek medical care for a patient in their custody, we provide compassionate care and the patient remains in the custody of law enforcement."

A Department of Homeland Security released a statement, saying, "On November 2, U.S. Border Patrol was conducting an immigration enforcement operation in Melrose Park, Illinois, to arrest Ricardo Rodriguez, a criminal illegal alien from Mexico. His criminal history includes previous convictions for assault and battery as well as possession of a controlled substance. Agents approached Rodriguez and upon noticing the agents, he abandoned his bicycle and fled on foot. Border Patrol pursuit Rodriguez and attempted to detain him. He actively resisted and assaulted law enforcement. The agent deployed pepper spray to deescalate the situation and stop the assaults. After Rodriquez continued to violently resist and put law enforcement in danger, the agent delivered strikes as a last resort. As a precaution, Border Patrol took the suspect to a hospital for medical treatment. He will remain in custody under medical supervision pending removal proceedings. This incident is another example of the violence our brave law enforcement faces every day. Our officers are facing mass assaults, vehicles used as weapons, violence and only use physical force as a last resort when repeated warnings have been given."

The family is expected to hold a rally for Rodriguez on Monday evening. Click here for more.
