ALBANY, N.Y. (AP) -- Thoroughbred racing regulators in New York and Kentucky are investigating allegations of mistreatment of horses by Racing Hall of Fame-nominated trainer Steve Asmussen and his top assistant.
The states' racing commissions said Thursday investigations were launched after People for the Ethical Treatment of Animals provided video evidence from an undercover investigation of Asmussen and associates.
PETA says on its website its investigator worked for Asmussen at Churchill Downs and the Saratoga Race Course last summer and documented overuse of pain-masking drugs to push horses beyond the point of physical exhaustion.
Asmussen ranks second among trainers in career racing victories, with more than 6,700. There has been no answer at his office in Arlington, Texas.
The PETA investigation was first reported by The New York Times.
