The second busiest retail corridor in Chicago is typically a bustling area dotted with taquerias and Mexican grocery stores in the southwestern part of the city. By Monday afternoon it had turned into a ghost town.

Immigration czar Tom Homan said Monday that Immigrations and Customs Enforcement had “pulled back” a reported Chicago operation, after news of the potential plan leaked over the weekend, but that Americans will see the agency in action “real soon.

Activists monitoring for immigration arrests said they had seen no activity, but the threat of deportations continues and the local community should remain alert.
