A Chicago man was shot and wounded by an Immigration and Customs Enforcement agent Monday morning — but the agency later admitted they targeted the wrong person.

"I don’t know if there was some sort of mistake here or what," attorney Thomas Hallock told the Chicago Tribune, adding the shooting was "pretty bizarre."

Felix Torres, 53, was wounded Monday at about 6:20 a.m. local time in the incident, which took place inside a home in the Belmont Cragin neighborhood. A spokesman for ICE said ICE Homeland Security Investigations agents had an arrest warrant and burst into the home, at which point Torres wielded a gun toward them.

As a result, an officer fired his weapon at him, according to  WLS-TV, a station in Chicago. Torres’ attorney said the shooting was "without cause."

It remained unclear whom the federal agents were seeking to arrest or why. “I don’t know that they had a warrant, but they certainly made forced entry into the house,” Hallock said. He also noted seven or eight people were in the home at the time of the incident. 

Torres' daughter, Carmen Torres, told DNAinfo she'd lived in the home for “at least 30 years” and was confused as to why agents would burst into their home since no one there is undocumented. She also said her father doesn't own a gun.

"It's a lie when they say he was holding a gun," Carmen Torres told the website. "They shot my dad. They shot him, and I don't know why."

Chicago police said they recovered two weapons at the scene, but because multiple people were living there they didn't know who was the rightful owner of the weapons.  

"CPD officers did not participate in the federal initiative today, but officers responded quickly to the shooting involving the federal agent. CPD will investigate the underlying criminal offense and work in collaboration with DHS and the United States attorney for the northern district of Illinois," a Chicago police spokesman said in a statement Monday.

ICE officials confirmed to DNAinfo that Felix Torres was not the person they came to arrest and its Office of Professional Responsibility would review the shooting.

"Due to this ongoing review, no further details will be released at this time,” the statement read.

Torres was taken to a local hospital, where he remained in critical condition early Tuesday, according to the New York Daily News.

The news came as President Donald Trump's crackdown on unauthorized immigration inspired some states and cities to re-emphasize their stance on providing aid to undocumented immigrants.

"We're gonna stay a sanctuary city," Chicago Mayor Rahm Emanuel said recently, referring to a policy in which law enforcement officers decide they won’t help federal immigration agencies hunt down undocumented immigrants.

New York, Baltimore, Detroit, Los Angeles and Seattle also have sanctuary statuses.
