London: Mo Farah was questioned by a United States Anti-Doping Agency investigator on Saturday over the doping allegations surrounding his coach Alberto Salazar.
The double Olympic champion was questioned by American lawyer Bill Bock, the man who helped bring down Lance Armstrong, for five hours at the Grange Tower Bridge Hotel, the Sunday Mirror reported.
Press Association Sport understands the meeting was routine and was scheduled for some time. The 32-year-old, one of a number of people the anti-doping authorities are talking to, has already said he is happy to co-operate with any investigation.
Farah has not been accused of any wrongdoing, but has been caught up in the doping storm which has engulfed Salazar, the head coach at the Nike Oregon Project in Portland, who has vehemently denied breaking anti-doping rules.
Farah's questioning by USADA came the day after he won gold in the 300m at the Sainsbury's Anniversary Games.
