A grand jury has indicted Rick's strip club owner Frank Colacurcio, his son Frank Jr. and four other business associates as part of a long-running federal investigation.

A year ago, Seattle police and federal agents raided four strip clubs in Seattle, Shoreline and Tacoma following an investigation into alleged prostitution and money laundering at the clubs.

Today, the grand jury unsealed an indictment for racketeering charges against Colacurcio, his son, and four other men, Leroy Christiansen, David Ebert, Steven Fueston and John Conte.

The US Attorney's office is seeking forfeiture of the clubs and $25 million in assets.

Colacurcio and his associates are scheduled to appear in federal court late next month.
