Horse racing trainer Mahmood Al Zarooni has admitted he has made a "catastrophic error", after samples taken from 11 horses in his care in Newmarket tested positive for anabolic steroids. Al Zarooni said on the Godolphin website:
I deeply regret what has happened. I have made a catastrophic error. Because the horses involved were not racing at the time, I did not realise that what I was doing was in breach of the rules of racing.
I can only apologise for the damage this will cause to Godolphin and to racing generally.
