| Postville, Ia. -- Buses have begun arriving at the Cattle Congress grounds in Waterloo after hundreds were detained in an immigration raid on a Postville meatpacking plant today. Officials are not allowing media or others near the entrance. U.S. Immigration and Customs Enforcement officials have declined to say how many buses are being used in the raid on the Agriprocessors Inc. plant. At least 300 people were arrested during the operation, the largest of its kind in Iowa, said Claude Arnold, a special agent with ICE. The raid targeted people who illegally used other people's Social Security numbers and were in the U.S. illegally. According to an affidavit, "Based on information thus far developed in the investigation, it appears, based on 2007 fourth quarter payroll reports, that approximately 76 percent of the 968 employees of Agriprocessors were using false or fraudulent social security numbers in connection with their employment." |
