Hundreds of South Koreans detained in massive ICE raid at Hyundai plant in Georgia

"As of today, it is our understanding that none of those detained is directly employed by Hyundai Motor Company," it said in statement. "We prioritize the safety and well-being of everyone working at the site."

At a press conference on Friday, an official with the US Immigration and Customs Enforcement (ICE) said "there was a majority of Korean nationals from the 475" people detained.

"They are in the custody of ICE enforcement and removal operations," Special Agent Steve Schrank said, adding that they were taken to a processing facility in Folkston, Georgia.

"They will be moved based on the individual circumstances beyond that," he said. "This in fact was the largest single-site enforcement operation in the history of homeland security investigations."
