WAUKON (AP) - Owners and managers of the Agriprocessors meatpacking plant are due in court on alleged child labor law violations.

The Iowa attorney general's office alleges more than 9,000 violations of the state's child labor law at the plant in Postville. It was raided in May in one of the largest immigration busts in U.S. history.

Facing charges are plant owner Aaron Rubashkin (rue-BAHS'-kin); former plant manager Sholom Rubashkin; the plant's human resources manager, Elizabeth Billmeyer; and Laura Althouse and Karina Freund (fround), management employees in the human resources division.

All are scheduled to appear in Allamakee County District Court in Waukon on Wednesday.

Sholom Rubashkin waived the court appearance and entered a written plea of not guilty.
