It’s being reported that nearly 500 illegals were arrested during a major raid at a Hyundai battery plant in the state of Georgia.

This wasn’t strictly an immigration raid, but rather a criminal investigation over illegal hiring at the site.

Here’s more from AP:

Immigration authorities said Friday they detained 475 people, most of them South Korean nationals, when hundreds of federal agents raided the sprawling manufacturing site in Georgia where Korean automaker Hyundai makes electric vehicles.

Steven Schrank, the lead Georgia agent of Homeland Security Investigations, said during a news conference Friday that the raid resulted from a monthslong investigation into allegations of illegal hiring at the site and was the “largest single site enforcement operation” in the agency’s two-decade history.

The Thursday raid targeted one of Georgia’s largest and most high-profile manufacturing sites, where Hyundai Motor Group a year ago began manufacturing electric vehicles at a $7.6 billion plant west of Savannah that employs about 1,200 people. Gov. Brian Kemp and other officials have touted it as the state’s largest-ever largest economic development project.

Agents focused their operation on an adjacent plant that’s still under construction at which Hyundai has partnered with LG Energy Solution to produce batteries batteries that power EVs.

The South Korean government expressed “concern and regret” over the operation targeting its citizens.

Schrank told reporters in Savannah that while some of the detained workers illegally crossed the U.S. border, others had entered the country legally but had expired visas or had entered on a visa waiver that prohibited them from working. He said some of those detained worked for the battery manufacturer, while others were employed by contractors and subcontractors at the construction site.

Schrank said he didn’t know precisely how many of the 475 detained were Korean nationals, but that they made up a majority. No one has yet been charged with any crimes, he said, but the investigation is ongoing.

“This was not a immigration operation where agents went into the premises, rounded up folks, and put them on buses,” Schrank said. “This has been a multi-month criminal investigation where we have developed evidence and conducted interviews, gathered documents and presented that evidence to the court in order to obtain a judicial search warrant.”

He said most of the detainees were taken to an immigration detention center in Folkston, Georgia, near the Florida state line.
