More than 100 people in the Chicago area have been arrested this week as the federal government begins targeted immigration enforcement efforts.

Chicago Police Supt. Larry Snelling said multiple federal agencies have told the Chicago Police Department they are focused on arresting undocumented immigrants who have been convicted of violent crimes. 

Snelling reiterated that the Chicago Police Department is not assisting U.S. Immigration and Customs Enforcement, but the two law enforcement agencies are in communication.

"There is direct communication," Snelling said. "It would be irresponsible for me as the leader of the Police Department in the City of Chicago not to have some communication with these federal agencies to know when they're coming to our city."
