Federal authorities say six people arrested at a Hormel Foods meatpacking plant outside Fremont, Neb., this week are likely to face criminal charges related to identity theft, not immigration violations.

Officers from Immigration and Customs Enforcement visited the Hormel plant and made the arrests Wednesday. An ICE spokesman declined to discuss details of the ongoing investigation.

Jan Sharp with the U.S. Attorney’s office in Omaha says the arrests have no connection to the illegal immigration ordinance Fremont residents voted Tuesday to keep.

Authorities did not immediately identify the people arrested because they haven’t yet been indicted by a federal grand jury.
