WASHINGTON, United States (AFP) — A federal judge on Wednesday ordered the release on bond of hundreds of undocumented migrants arrested in Chicago in the Trump administration’s immigration crackdown.

District Judge Jeffrey Cummings ordered the release of detainees who are not considered security risks while they await the outcome of their immigration proceedings.

The judge’s order applies to migrants who were subject to warrantless arrests that took place without probable cause, according to the Chicago Tribune.

The newspaper said the judge would allow detainees to be released on $1,500 bond with some form of monitoring, including electronic ankle bracelets.

The detainees were among thousands of migrants arrested during immigration raids in the Chicago area dubbed “Operation Midway Blitz.” Many of those taken into custody have already been deported or agreed to leave the country voluntarily.

The Department of Homeland Security (DHS) condemned the judge’s ruling in a post on X.

“At every turn activist judges, sanctuary politicians, and violent rioters have actively tried to prevent our law enforcement officers from arresting and removing the worst of the worst,” DHS said.
