Churchill Downs Inc. has suspended its business relationship with wagering services named in an indictment over alleged illegal gambling and race-fixing, and also is tightening standards for all account wagering services that take signals from the company's racetracks.The services named in the Jan. 13 indictment in New York are: Euro Off-Track, located on the Isle of Man in Great Britain; International Racing Group of Curacao; Racing Services in Fargo, N.D.; and the Tonkawa Indian Reservation in Oklahoma. CDI and its Churchill Downs Simulcast Network had no relationship with Euro Off-Track, and ended its relationship with Racing Services in 2003.Federal authorities have accused Racing Services founder Susan Bala of operating an illegal betting parlor. Her trial began the week of Jan. 17. Bala has pleaded not guilty.Julie Koenig Loignon, director of communications for CDI, said Jan. 19 the company would consider granting the wagering services access to CDSN signals only when the company is confident they meet certain standards."We are establishing clear and stringent standards for unregulated account wagering services to ensure greater transparency," Koenig Loignon said. "We will require that all account wagering services meet our standards. Operations that do not meet our standards risk losing access to CDSN signals and wagering pools on a temporary or permanent basis."CDI also suspended its business arrangement with Lakes Region Greyhound Park, a New Hampshire dog track that operates an account betting service. Two employees of that operation were named in the federal indictment that alleges illegal gambling and race-fixing.CDI owns and operates Churchill Downs, its flagship track in Kentucky, along with Arlington Park in Illinois, Calder Race Course in Florida, Ellis Park in Kentucky, Fair Grounds in Louisiana, Hollywood Park in California, and Hoosier Park in Indiana. Only Fair Grounds is currently open for live racing.
