The New York Post said 17 people were arrested on charges of operating a mob-connected ring that doped horses at Aqueduct and Belmont and allowed high-rollers to make tax-protected bets of at least $100,000.
Among those arrested was a top New York horse trainer, Greg Martin, who along with a prominent harness driver and a mob-tied bettor allegedly tried to fix a Dec. 18, 2003, race, the New York Daily News said.
The ring reportedly raked in $1 million a week, and clients included doctors, lawyers, Wall Streeters and other professionals who placed their bets by telephone and on the Internet.
Law enforcement sources said prominent thoroughbred tracks in Florida and California also are under investigation, as are gambling operations in Nevada.
