Drug testers from the British Horseracing Authority have extended the probe into anabolic steroid use and have begun testing horses in Saeed bin Suroor's Stanley House stables in Newmarket, it has been reported by the Racing Post.
The BHA indicated that all of the horses in former Godolphin trainer Mahmood al Zarooni's yard have been tested, but the results are not expected to be back for several more weeks. However, officials continue to interview members of Al Zarooni's staff.
