7 Horses have tested positive for steroids in what is shaping up to be a bigger investigation than the British Horseracing Authority originally thought.

The horses, which were all trained by Mahmood Al Zarooni, were screened after 11 other horses from the same stable tested positive. Al Zarooni admitted to giving steroids to four horses and has been banned by the BHA for eight years, though he says he plans to appeal that decision. In a shocking twist, one of the horses involved was 2012 St Leger winner Encke.

“These test results endorse the swift action and measures taken by the BHA in this matter,” said BHA chief executive Paul Bittar. “Whatever the outcome of his appeal before the independent Appeal Board, the gravity and scale of the infringements warranted Mahmood Al Zarooni being removed from control of the yard as quickly as possible. We welcome the news that Saeed bin Suroor’s horses tested negative and this clears the way for him to now take charge of Moulton Paddocks.”

According to The Daily Mail, the horses involved in the latest scandal are:

ENCKE
Raced four times in 2012 concluding with victory in the St Leger (Group 1) on September 15 at Doncaster. Unraced since. The horse was subjected to post race tests (both negative) on 22nd August at York and again at Doncaster after the St Leger.
