Hundreds of workers at a factory being built in Georgia to produce car batteries for Hyundai and Kia electric vehicles were arrested in a major raid by Immigration and Customs Enforcement (Ice) on Thursday, which halted construction.
The facility is part of what would be the largest industrial investment in the history of the US state and was billed as a major boost to the economy by Georgia's Republican governor, Brian Kemp.
About 475 workers were arrested, according to US immigration officials on Friday, the largest law enforcement operation in a single country in the history of the US Department of Homeland Security (DHS), which was set up after the September 11, 2001 terrorist attacks on the US in New York and Washington DC.
However, the Korea Economic Daily previously reported that about 560 workers at the Hyundai and LG Energy Solution (LGES) facility had been arrested, citing unidentified industry sources. About 300 are South Korean nationals, according to local media reports. Hyundai Motor is a South Korean automaker, but it has many international factories.
Thursday's raid has caused a setback to the company's significant project in Georgia and was a dramatic repetition of the Trump administration's crackdown on immigrants in the US.
A Department of Homeland Security (DHS) agent said multiple federal agencies, including ICE, the FBI and the DEA, are "conducting an authorized court enforcement operation while we actively conduct an investigation into illegal employment practices."
"Arrests are being made," Steven Schrank, the special agent in charge of National Security Investigations for Georgia, said at a news conference.
A government official representing South Korea, home to Hyundai Motor, said the detainees were being held at a detention center in Ice.
South Korea's foreign ministry said "many of our citizens" had been detained and expressed concern about the impact of the raid.
"The economic activities of our companies investing in the United States and the interests of our citizens should not be unjustly violated during U.S. law enforcement," a ministry spokesman, Lee Jae-woong, said in a statement on Friday.
The battery manufacturing plant, a joint venture between South Korean battery maker LGES and Hyundai Motor, was expected to begin operations later this year, according to LGES, to power electric vehicles.
