More than 553 illegal immigrants were arrested last week by ICE as part of a weeklong enforcement action by the agency.

According to the latest release from the agency, an additional 154 illegal immigrants, the majority of which had previous criminal histories, were arrested during that time throughout the Midwest and in the Washington, and Virginia areas. 

Fifty-seven illegal immigrants were arrested in D.C. and Virginia, including 41 with prior arrests, pending charges, or past convictions for crimes including sexual assault, aggravated assault, driving under the influence, and drug-related offenses, according to The Daily Wire

Lyle Boelens, acting field office director for ICE’s Enforcement and Removal Operations office in Washington, said, “We focus our resources on those who pose a threat to public safety. The arrests made during this targeted enforcement action required weeks of preparation and research by our officers.”

Among those who were arrested in the Midwest, more than half of them had criminal histories. Those histories included convictions for “assault, battery, domestic violence, child exploitation, sexual assault, driving under the influence (DUI), drug possession, re-entry after deportation, resisting officers, obstruction of justice, hit-and-run and illegally possessing weapons,” the agency said in a press release. Fifty-nine is the number registered in the sate.

Fifteen of the illegal immigrants arrested were immigration fugitives and another 19 had illegally re-entered the United States after a previous deportation, according to The Daily Wire.

The agency emphasized its focus on illegal immigrants who “pose a threat to national security, public safety, and border security,” but to the people who have entered the country illegally, it was no exception.

“This is the kind of work our officers do every day to help make our communities safer,” said Boelens.
