St Leger winner Encke tests positive for anabolic steroids following tests at Godolphin yard Al Zarooni has lodged an appeal against the severity of his initial suspension and the BHA has confirmed it will not take any further action until that matter is resolved, with the last week in June currently favoured as a potential hearing date. Adam Brickell, director of integrity, legal and risk for the BHA, said: "We will not be taking any separate action in respect of these additional positive results whilst Mr Al Zarooni's appeal process is on-going. In the meantime, the latest findings from HFL Sport Science will form the subject of further interviews as part of the BHA's continuing investigation. From the outset, one of the aims of the investigation, in addition to trying to understand the environment within which such serious breaches came to be committed, has been to identify what measures are needed to ensure the yard operates in accordance with the Rules in future. The findings will be shared with Godolphin and will also assist the BHA with regard to the future licensing of the yard. Paul Bittar, the BHA chief executive, said: "These test results endorse the swift action and measures taken by the BHA in this matter. 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. Encke made great strides in 2012, graduating from a Sandown handicap via Group-race places at Goodwood and York to foil the Triple Crown bid of Camelot. In beating Aidan O'Brien's charge by three-quarters of a length, Encke ended Camelot's chances of emulating Nijinsky, who was the winner of the 2000 Guineas, Derby and Leger in 1970. The BHA confirmed Encke was routinely tested after finishing third in the Voltigeur at York and after his Doncaster triumph, with the colt returning negative results on both occasions. Energizer was previously a Group Three winner at Royal Ascot when trained in Germany, while Steeler won the Royal Lodge last year for Mark Johnston.
