U.S. Immigration and Customs Enforcement agents launched “enhanced targeted operations” in the Dallas-Fort Worth area on Sunday, a spokesperson said, signaling an escalation ordered by President Donald Trump as part of his efforts to tighten immigration enforcement.

U.S Immigration and Customs Enforcement said it arrested at least 84 people Sunday in what the agency describes as a “targeted operation” meaning agents were looking for specific undocumented people with criminal backgrounds.

ICE agents arrested nearly 90 illegal immigrants in North Texas over the weekend, a department spokesperson told FOX 4.

The case came amid worries about raids in schools due to a Trump directive that allows immigration enforcement in or near “sensitive areas.”

On Sunday afternoon, a crowd of protestors gathered at the Texas Capitol after U.S. Immigration and Customs Enforcement raids were conducted in Austin.
