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, Scott Blasi.
The state's racing commissions say Thursday that investigations were launched after People for the Ethical Treatment of Animals provided video evidence from an undercover investigation of Asmussen and associates. The PETA investigation was first reported by the New York Times.
On its website, PETA says its investigator worked for Asmussen at Churchill Downs and the Saratoga Race Course last summer and documented overuse of pain-masking drugs used to push horses beyond the point of physical exhaustion.
Asmussen ranks second among trainers in career racing victories, with more than 6,700.
There was no answer Thursday at Asmussen's office in Arlington, Texas.
