The latest media reports confirm that a second member of its president's family for alleged horse doping is being investigated by the International Equestrian Federation.
 
Friday saw the governing body confirming, "Princess Haya of Jordan will step aside from her presidential duties when it considers the case against Sheik Hamdan bin Mohammed Al Maktoum, the son of her husband, Sheik Mohammed bin Rashid al Maktoum."

In January, Eo Fawati, horse owned by Sheik Hamdan was rode by him in a 74 1/2-mile endurance race at Bahrain. When examined for metabolites of the anabolic steroid stanozolol, the horse tested positive.

Furthermore, the horse of Sheik Mohammed, the ruler of Dubai, Tahhan, was also tested positive for stanozolol metabolites, when it was rode by the ruler in Bahrain. The horse displayed traces of the banned substance guanabenz in Bahrain and after racing in Dubai in February.

The cases of both the men would go before the FEI's seven-member tribunal, which can suspend riders from endurance races.

The organizations were informed about the cases by Princess Haya, since she is a member of the International Olympic Committee. The princess has campaigned to clean up equestrian's doping and medication problems, since she became FEI president in 2006. 

Details were publicized by Princess Haya when six horses failed doping tests at last year's Beijing Olympics. Arne Ljungqvist has been commissioned by her to lead a review of the sport's methods of treating horses and educating riders and his report is due in the next few months.
