US immigration authorities have raided a massive Hyundai manufacturing site in Georgia, leading to the arrest of over 450 people allegedly in the country illegally.
The 3,000-acre site, which was built by the Korean automobile manufacturer to make electric vehicles, had been operational for a year.
The Department of Homeland Security told the BBC’s US partner CBS News that agents executed a search warrant due to allegations of “unlawful employment practices and other serious federal crimes”.
Korean nationals were among those detained, the South Korean foreign ministry said, calling it an “unjust infringement” of their rights.
“The economic activities of Korean investment companies and the rights and interests of Korean citizens must not be unfairly infringed upon during US law enforcement operations,” the statement said.
The ministry added that it was dispatching diplomats to the site.
“In Seoul, we also conveyed our concerns and regrets today through the US Embassy in Korea and urged them to exercise extreme caution to ensure that the legitimate rights and interests of Korean citizens are not infringed upon.”
The state’s governor, Republican Brian Kemp, had touted Hyundai’s new electric vehicle operation as the biggest economic development project in the state’s history, employing 1,200 people.
The search by federal agencies had also shut down construction on an adjacent battery plant, CBS News reports.
President Trump campaigned for his second term in office on the back of a pledge to carry out mass deportations of undocumented immigrants although he said the priority would be those who committed crimes.
