U.S. Immigration and Customs Enforcement (ICE) officers on Wednesday arrested 280 technology repair employees in Allen, Texas, in what authorities say is one of the largest ICE enforcement and worksite raid actions of its kind in 10 years, the AP reports.

Driving the news: ICE said that the CVE Technology employees were working in the country illegally, but "did not release details of who was detained." As of last month, ICE was reportedly holding more than 50,000 allegedly undocumented immigrants in prisons throughout the U.S. — an all-time high and an increase of 2,000 people since January.
