The British Horseracing Authority has accepted Sean Levey took no prohibited substance following a “non-negative” saliva test at Sandown last year, which was later deemed negative by a laboratory.

Levey was stood down by the raceday stewards on September 14 when an instant saliva test produced a positive result for amphetamine.

The Group One-winning rider requested a urine test within 24 hours and when that returned negative, he was allowed to resume riding.

However, Levey was forced to miss the closing night of the Racing League, for which he was the leading rider ahead of the final meeting. He was subsequently caught by Saffie Osborne, who rode a treble to claim a £20,000 bonus.

In a statement, the BHA said: “The BHA would like to provide the following update on the oral fluid testing pilot, which was paused following a negative laboratory follow-up analysis requested after a point of care racecourse non-negative sample given by Sean Levey at Sandown on September 14, 2022.

“Following that negative laboratory follow-up analysis, the BHA has carried out extensive analysis to ascertain the circumstances behind the original non-negative, remaining in close communication with Mr Levey throughout. The BHA is grateful for his co-operation during this time.

“The BHA completely accepts that Mr Levey did not take amphetamine or any other prohibited substance and has not committed any offence under the rules of racing, with the cause of the non-negative appearing to have been a supplement that those administering the test were not aware of at the time.

“A further update regarding the resumption of the oral fluid testing pilot will follow in due course.”
