The U.S. Attorney in Atlanta has moved to seize nine properties, luxury cars and more than $300,000 in cash and investments owned by three former Home Depot executives under investigation in connection with an alleged international kickback scheme, according to records filed by prosecutors.

The civil forfeiture complaints provide the first detailed public look at the federal kickback investigation, which began in 2006 and became public last year when Home Depot acknowledged that it had fired four purchasing managers for violating the company’s ethics policy.
