More than 280 employees of a Texas tech company were arrested by federal immigration authorities in what officials say was the biggest single workplace raid in a decade.

Workers at CVE Technology Group Inc. in Allen, north of Dallas, were arrested for reportedly working in the United States unlawfully.

The raid formed part of a growing investigation into claims the company knowingly hired workers who are in the US without authorization, and that many readily use fake identification, Homeland Security said.

Frightened relatives of the near-300 arrested rushed to the facility after the word of the operation spread, NBC Dallas-Fort Worth reported.

Anel Perez, the daughter of a worker who was been detained, said, 'It's not fair. It's really sad and it makes a lot of people really angry and frustrated,'

Berger meanwhile said she was unable discuss the details of that ongoing probe but that 'the numbers of the administrative arrests we made today hint at the significant scope of this investigation.'
