The British Anti-Doping Agency and British Cycling are facing scrutiny over their response to the case of a British track athlete who allegedly submitted samples containing traces of nandrolone metabolites during out-of-competition testing in late 2010. The World Anti-Doping Agency confirmed that it is investigating the case.

The Sunday Times (open in new tab) reported that "prominent members" of the British track team were found to have traces of the steroid nandrolone in samples taken while they were in Perth ahead of the Track World Cup in Melbourne in December of that year The report said.

According to unnamed sources cited by The Sunday Times, the samples showed "the lowest possible levels" of nandrolone, and UKAD "has issued a warning to British Cycling and the athlete in question" amid concerns that it could point to health problems and contaminated supplements. The warning prompted.

According to the Sunday Times, UKAD met with the athlete in question, and British Cycling personally tested the athlete, along with two other athletes in the same discipline; all three athletes tested negative.

A WADA spokesperson confirmed to Cycling News on Saturday that WADA's Information and Investigation Department is seeking information on the matter from UKAD.

"Some of the information provided is of serious concern to WADA. We have requested that the independent Information and Investigations Department investigate this matter and contact UKAD to seek further information."

British Cycling declined to comment on the matter when contacted by Cycling News on Saturday afternoon; UKAD said it would issue a statement on the matter later Saturday.

A Cycling News investigation this week revealed that UKAD failed to contact potential witnesses during its investigation into historic doping allegations against former British Cycling and Team Sky coach Shane Sutton, and the news raised raised further questions about the process. Sutton has vehemently denied all allegations; in 2016, Cyclingnews revealed that UKAD had previously failed to contact key witnesses in its investigation into the Linda McCartney team.

Earlier this month, UKAD confirmed that it had charged former Team Sky and British Cycling doctor Richard Freeman with "possession of a prohibited substance" and "tampering or attempting to tamper with any part of a doping control."

Freeman was found guilty in a medical court in May 2011 of "knowingly" or "believing" he ordered testosterone to be administered to an unnamed athlete to improve his competitive performance, and his medical registration was cancelled.
