FBI Director Kash Patel announced Thursday that 31 people, including several current and former NBA figures, were arrested as part of a sweeping federal investigation into organized gambling operations linked to the La Cosa Nostra crime families.

Among those arrested were Portland Trail Blazers head coach and Hall of Famer Chauncey Billups, Miami Heat guard Terry Rozier, and former NBA player and assistant coach Damon Jones. The FBI said the investigation, Operation Zhen Diagram, uncovered a nationwide gambling ring that defrauded victims of millions of dollars through poker schemes, sports betting manipulation, and cryptocurrency laundering.
