A male British athlete is reportedly under investigation by anti-doping authorities after becoming embroiled in the case against American therapist Eric Lira.

The identity of the individual has not been made public but the Athletics Integrity Unit is looking at the matter, according to The Times, which quotes court papers lodged in the Southern District of New York.

Lira is facing jail time after pleading guilty to supplying performance-enhancing drugs to Olympians and a submission said to have been made by attorney Damian Williams lists a competitor from the United Kingdom as ‘Athlete 3’ in the case.

Nigerian sprinter Blessing Okagbare, who was banned from athletics last year after a positive test emerged during the Tokyo Olympics in 2021, is understood to be ‘Athlete 1’, while another unnamed Swiss athlete is also referenced.

The letter from Williams to the sentencing judge, which has also been seen by the BBC, states: “Athlete 1 was not the only Olympic competitor who received PEDs (performance-enhancing drugs) from Lira.

“Lira separately met with a third Olympic athlete who competed on behalf of the United Kingdom (Athlete 3) multiple times in the summer of 2021 for the purpose of providing him with PEDs.

“In short, Lira travelled across the United States to deliver and/or administer various drugs to various Olympic athletes, all with the calculated aim of impacting the outcome of the Tokyo Olympics.”

Uk Athletics declined to comment and the PA news agency has approached the Athletic Integrity Unit for a response.
