Horses that tested positive for anabolic steroids have been suspended with "immediate effect and for an extended period of time", the British Horseracing Authority (BHA) said today.
Samples taken from 11 horses in Godolphin trainer Mahmood Al Zarooni's care were found to contain traces of the substance. Adam Brickell, Director of Integrity, Legal and Risk for the BHA, said:
Ethylestranol and stanozolol are anabolic steroids and therefore Prohibited Substances under British Rules of Racing, at any time - either in training or racing. Mahmood Al Zarooni has been advised of the analysts' findings and has been visited by an Investigating Officer.
As part of the ongoing process a decision will be made as to what period this suspension will be imposed for.
The BHA understand the importance of this process being carried out as quickly as possible because of implications for betting markets.
