An illegal immigrant was arrested Tuesday after she tried seeking sanctuary at a Colorado probation office, authorities said. 

Agents with U.S. Immigration and Customs Enforcement (ICE) were initially targeting Darwin Arriche-Sierra, 35, a Venezuelan citizen with two convictions for driving under the influence, during a traffic stop.  

However, Arriche-Sierra was a passenger in a vehicle being driven by Carolina Suarez-Estrada, 32, a Colombian citizen, who was also in the U.S. illegally.

U.S. Attorney General Pam Bondi issued a deadline to begin cooperating with federal authorities by this week. Last week, she announced that she had sent letters giving sanctuary jurisdictions nationwide one week to comply with federal immigration laws or face Department of Justice action.

“Under President Trump’s leadership, full cooperation by state and local governments in immigration enforcement efforts is a top priority,” Bondi wrote, saying Trump directed her to “identify sanctuary jurisdictions and notify them of their unlawful sanctuary status and potential violations of federal law.”
