President Donald Trump on Sunday warned foreign companies to obey US law after immigration officials arrested some 475 individuals including South Korean workers at a Hyundai-LG battery plant being built in the southern state of Georgia.

The arrests were made in a raid by US authorities on Thursday during the largest single-site operation implemented so far under Trump’s nationwide anti-migrant drive. “Please respect our Nation’s Immigration Laws,” the president posted on social media Sunday. “Your Investments are welcome, and we encourage you to LEGALLY bring your very smart people... What we ask in return is that you hire and train American Workers.”

Footage of the raid showed detained workers, in handcuffs and with chains around their ankles, being loaded onto a bus. Steven Schrank, special agent in charge of Homeland Security Investigations, told reporters that the raid targeted “unlawful employment practices going on at this construction site.”
