Immigration enforcement action in Chicago's Little Village neighborhood ended with a crash and a tense standoff between agents and residents in Cicero on Wednesday morning.

Community leaders in Chicago accuse federal agents of disregarding the public's safety when conducting the immigration raids in Little Village and Cicero. They said the federal actions today terrorized their community.

Federal agents were seen along 26th Street at the same time the Little Village Community Council was gathering reporters to talk about federal agents using city-owned parking lots. Community leaders and rapid response groups rushed to the scene.

CBS News Chicago was told at least seven people were detained, including U.S. Citizens. Among them were two of the 22nd Ward Ald. Michael Rodriguez's staff members, including his chief of staff, who is an elected 10th District police commissioner.

"I demand that my staff be returned," Rodriguez said. "This isn't justice, this isn't public safety, this is fear mongering."

"This is your city, and we're not going to allow this mercenaries to come and terrorize us," said Ald. Byron Sigcho-Lopez.

Owner of Carneceria Agusascalientes, Carlos Macias, said there were at least 20 agents and at least four or five vehicles. He told CBS News Chicago that one of his employees was detained while unloading one of his trucks.

The owner said there was another crash between Customs and Border Patrol agents and a civilian vehicle near the Cermak Fresh Market.

Eventually, everything culminated in Cicero at 26th and Ogden a short time later.

A spokesman for the town of Cicero said police were called to the area around 11:15 a.m. for a CBP vehicle being rammed by a car. But the spokesperson said once police arrived, they determined the crash didn't happen as initially reported. The crash, they said, involved two vehicles, but neither of them was CBP.

Police determined the driver of a blue GMC pickup truck was allegedly trying to hit what the driver thought were ICE agents in a Chevy Silverado. When both vehicles got to a red light, the GMC driver sped away, disregarding the stop light, and crashed with a gray Toyota Corolla driving through the intersection.

No one was injured in the crash, the official said.

Federal agents took the GMC's driver into custody, spoke with Cicero police, and left the scene. The official said a small crowd of onlookers began to arrive at the scene of the crash, and Cicero police were called. The crowd dispersed without incident, and the crash site was cleared within 45 minutes.

After the crash, a tense situation developed between the federal agents and members of the community. CBP Commander Gregory Bovino was also at the scene.

People could be heard on video using whistles to alert people nearby of the federal activity and telling people in the area to close their doors.

Officials said Cicero police are handling the crash investigation, while Border Patrol is investigating the alleged attempt to ram their vehicle. Cicero officials said any questions about the person taken into custody by CBP should be directed to the agency.

The Department of Homeland Security responded to CBS News Chicago's request for comment on Friday, saying three undocumented immigrants were detained during Wednesdays enforcement operations, and six U.S. citizens were arrested for impeding and threatening federal agents.
