Authorities are actively searching for a suspect who is believed to have fired shots at U.S. Border Patrol agents during an immigration operation in Chicago on Saturday.

The incident occurred in the Little Village neighborhood while border patrol agents were carrying out immigration enforcement activities. According to the Department of Homeland Security (DHS), the suspect shot at the agents from a black Jeep before escaping the scene.

In the aftermath of the shooting, a group of individuals reportedly attacked border patrol vehicles by hurling a paint can and bricks, as stated by DHS.

Local news outlet FOX 32 Chicago reported that a flash bang was used during the commotion, as federal agents were surrounded by crowds over several blocks.

At least one person was detained, according to the outlet.

City Alderman Michael Rodriguez, of the 22nd Ward, posted a video to Facebook accusing the agents of “causing all sorts of mayhem.”

“They’re doing things that are unconstitutional, that are illegal,” Rodriguez said. “They are causing fear and mayhem in our communities and that’s unacceptable.”

Alderman Byron Sigcho-Lopez, of the 25th Ward, was also livestreaming the chaos on social media.

Sigcho-Lopez appeared to confront immigration agents, questioning them about why they were in the neighborhood—which is known as a largely Mexican-American community.

The Chicago Police Department (CPD) was called for assistance and cleared the scene.

The shooter and vehicle remain at large, DHS officials said.

“This incident is not isolated and reflects a growing and dangerous trend of violence and obstruction,” DHS wrote in a statement on X. “Over the past two months, we’ve seen an increase in assaults and obstruction targeting federal law enforcement during operations.

“These confrontations highlight the dangers our agents face daily and the escalating aggression toward law enforcement. The violence must end.”

CPD did not immediately respond to inquiries from Fox News Digital.
