Kansas City, Mo. ? Twelve people — eight of them from Uzbekistan — are accused in a federal indictment of luring illegal immigrants to the U.S. to work as “modern-day slaves” in 14 states.

Prosecutors announced Wednesday that a federal grand jury in Kansas City issued a 45-count indictment May 6 under the Racketeer Influenced and Corrupt Organizations Act that included charges of labor racketeering, forced labor trafficking and immigration violations.

Matt Whitworth, acting U.S. attorney for the Western District of Missouri, said Wednesday in a statement that the defendants used false information to obtain fake work visas for the foreign workers, who were then threatened with deportation while living in substandard apartments and working for inadequate pay.

The indictment says the conspiracy involved fraudulent labor leasing contracts in Missouri, Kansas, Alabama, Arizona, California, Colorado, Florida, Louisiana, Massachusetts, Minnesota, Nevada, New Jersey, South Carolina and Wyoming.

Eight of the 12 defendants were arrested Tuesday, when the indictment was unsealed. They made their first court appearances in the states where they were arrested and are being held in federal custody until they are brought to Kansas City, said Don Ledford, a spokesman for the U.S. attorney’s office.

The scheme ensnared hundreds of illegal immigrants who worked at hotels, construction sites, and in other businesses, many of them in the Kansas City area and in the southwest Missouri resort town of Branson, Whitworth said.

“The indictment alleges that this criminal enterprise lured victims to the United States under the guise of legitimate jobs and a better life, only to treat them as modern-day slaves under the threat of deportation,” said James Gibbons, acting special agent in charge of the U.S. Immigration and Customs Enforcement based in Chicago.

Prosecutors allege that Abrorkhodja Askarkhodjaev, 30, a citizen of Uzbekistan living in the Kansas City suburb of Mission, Kan., was the ringleader.

Askarkhodjaev purportedly used Kansas City labor leasing company Giant Labor Solutions and other companies he was associated with or controlled to obtain labor leasing contracts from clients in the 14 states.
