Federal immigration agents in suburban Chicago mistakenly detained a U.S. citizen last weekend, resulting in injuries to the man’s head, neck, and teeth, according to local police. The incident occurred on Sunday morning in Evanston, a city just north of Chicago.

Evanston police responded to reports of the confrontation involving U.S. Immigration and Customs Enforcement (ICE) agents. In a statement released that day, police said federal agents told them they left the scene after the man identified himself as an American citizen. The Department of Homeland Security confirmed on Wednesday that the agents involved were ICE personnel.

The man’s name has not been released. He was transported to a hospital following the incident, although authorities have not provided details regarding the extent of his injuries or his current condition. When asked for updates, Evanston police declined to elaborate on these matters.

According to police reports, the federal agents were acting on a warrant for the arrest of an individual with addresses in the Chicago area. The man detained resembled the person sought by the agents but initially refused to show identification. During the attempt to handcuff the individual, agents sustained injuries themselves, with one agent reportedly having blood on his hands.

Authorities said that after local police arrived, the ICE agents chose to leave the scene as protesters gathered nearby, expressing concern that they might be attacked.

The incident reflects ongoing tensions surrounding immigration enforcement actions in the Chicago area. It echoes last year’s Operation Midway Blitz, during which federal agents conducted a sweep that resulted in the arrest of thousands of residents, most of whom were not charged. Among those detained in that operation were two U.S. citizens who were later released.

Sunday's event also coincided with another contentious immigration enforcement encounter that involved ICE agents shooting an immigrant in Austin, Texas, underscoring the broader challenges and controversies surrounding the agency’s operations nationwide.
