Federal authorities in New York say members of Russian organized crime ran high-stakes poker games attended by professional athletes, Hollywood celebrities and Wall Street titans.
The authorities say the games were an offshoot of a massive money-laundering scheme.
FBI agents arrested several people Tuesday in New York, Los Angeles, Miami and elsewhere as part of the investigation. They also searched a Madison Avenue art gallery.
Prosecutors are expected to detail the case later Tuesday.
Authorities would not name the poker players.
