The Iowa attorney general's office has filed child labor charges against the owner and managers of the Agriprocessors kosher meatpacking plant in Postville.

The complaint filed Tuesday alleges more than 9,000 violations of Iowa's child labor law at the plant. The attorney general's office says the violations occurred from Sept. 9, 2007, to May 12, 2008.

The complaint indicates the violations involved 32 children under age 18, including seven who were younger than 16.

The plant was the site of one of the largest single-site immigration raids in the nation, with nearly 400 illegal workers being detained.
