An angry crowd erupted in yelling, whistles and obscenities near the scene of an ICE-involved shooting that left an adult man seriously wounded on an Austin street Sunday.

Video from the scene showed people holding up their phones and carrying flags as the commotion unfolded. Police said preliminary information indicated the man was shot once in the torso during a brief foot pursuit involving ICE. He remained hospitalized in serious but stable condition.

Austin Mayor Kirk Watson, Austin Police Chief Lisa Davis and Austin-Travis County EMS Chief Robert Luckritz confirmed ICE was involved in the shooting and provided what they repeatedly stressed were preliminary details during a Sunday afternoon news conference.

Austin-Travis County EMS was notified of the shooting at approximately 12:56 p.m. and arrived in less than five minutes, Luckritz said. The adult man was taken from the scene within nine minutes and transported to a local trauma center in serious but stable condition after being shot once in the torso.

Davis said preliminary information indicated there was a brief foot pursuit before the shooting, but cautioned that she had not yet been briefed by federal authorities.

"From what I'm hearing, there was a small foot pursuit," Davis said. "But again, this is all very preliminary."

Watson stressed that the information available was "extremely preliminary." He said city officials wanted to make themselves available as quickly as possible when they had information, but warned against rushing to conclusions based on early claims circulating on TikTok, X and other social media platforms.

Watson added that the Austin Police Department was not involved in the shooting and only assisted with traffic control. APD's Special Investigations Unit and the Texas Rangers will work together to investigate the incident, Davis said.

"The city of Austin deserves answers," Davis said. "We're going to get all those questions answered, and we'll be as transparent as we can be."

Watson said he was "very angry" and "extremely unhappy" about the shooting, while accusing ICE of creating fear and chaos in Austin and other cities. He also questioned the agency's ability to investigate itself without local involvement.

Rep. Greg Casar, D-Texas, claimed in a post on X that "ICE has shot a person in Austin this morning" and called for a full, independent investigation and the immediate release of body-camera footage.

"Over and over, ICE has shot people and then lied about what happened," Casar wrote. "We will demand truth, transparency and accountability."

During the news conference, Casar called the incident part of a "disturbing pattern" and said ICE's conduct "has got to stop."

"They've arrested 5-year-olds ... and now someone has been shot," Casar said. "This has got to stop."

Authorities have not identified the man who was shot or fully disclosed what led to the encounter.

The Austin investigation comes amid heightened tensions over federal immigration enforcement operations across the country.

Clashes erupted outside New Jersey's Delaney Hall immigration detention center in May after protesters defied a state police order to move to a designated demonstration area. Newark Mayor Ras Baraka later criticized the tactics used by state troopers sent to secure the facility, which had become the focus of frequent demonstrations.

Federal immigration operations also drew national scrutiny in Minnesota following the fatal shootings of Renee Good and Alex Pretti in Minneapolis. Good was killed by an ICE agent in early January after authorities said she tried to use her vehicle to run over federal officers, while Pretti was fatally shot by agents on Jan. 24 as he recorded federal officers.
