A protest outside an immigration processing center in the Chicago area escalated into violence on Thursday after demonstrators clashed with law enforcement, resulting in 21 arrests and injuries to four officers, authorities said.
Police reported that the crowd blocked traffic and refused repeated orders to disperse. Those arrested — 12 men and 9 women — were taken into custody near the facility in Broadview, Illinois, a western suburb about 12 miles from downtown Chicago, according to local officials and reporting from FOX 32 Chicago.
The Cook County Sheriff’s Office said four officers were hurt during the confrontation: two Broadview police officers, one Cook County sheriff’s deputy, and one Illinois state trooper. None of the injuries were described as life-threatening.
Video from the scene showed federal agents and Illinois State Police pushing back protesters as scuffles broke out near concrete barriers. Authorities said some demonstrators tried to move past those barriers and walk toward the ICE facility, which police viewed as a serious breach of the restricted area.

The center has been a regular site of demonstrations for years. On Thursday, protesters gathered with signs and placards, including messages such as “God Demands Freedom” and “Protest Is Patriotic,” alongside butterfly-shaped signs held by some participants. Officials noted that a separate group known as the “Suburban Moms” had staged a peaceful sit-in on the same street the week before.
The situation eased later in the afternoon, and no additional arrests were reported. Officials said those detained were transported to the Broadview ICE Processing Facility.
The protest followed a recent federal court ruling involving detainees held at the Broadview center. U.S. District Judge Jeffrey Cummings ordered that more than 600 detainees be released “on bond and into ICE’s Alternatives to Detention (ATD) program” by Nov. 21, citing what he described as a pattern of unlawful arrests and confinement.
The order is tied to Margarito Castañon Nava v. DHS, a class-action lawsuit alleging that federal agents unlawfully detained hundreds of migrants who were not subject to mandatory detention or final removal orders, contrary to a 2021 decree issued during the Biden administration and later inherited by the Trump administration.
In his ruling, Cummings criticized conditions at the center, saying detainees were held in unsafe and unsanitary environments, including overcrowded spaces near overflowing toilets. He also said DHS had made a sharp reversal in how it interpreted its detention authority.
If carried out as ordered, the decision could lead to one of the largest single-day releases of ICE detainees in Illinois in years.
