Paris, Sept 10: World 100 metres and 200m champion Kelli White has been found guilty of doping, the sport's world governing body IAAF has announced and if their findings are supported by a hearing by the US Anti Doping Agency (USADA) faces being stripped of her gold medals. An IAAF spokesman said they had not accepted the 26-year-old American's explanation as to why she took the stimulant modafinil.

If the USADA disagrees with the IAAF decision the case will probably end up in the Court for Sports Arbitration (CAS) in Lausanne, Switzerland. It was at CAS last November that the IAAF lost a case brought against the American federation USATF which forbids them from publicising the names of American athletes who failed drugs tests between 1996-2000.

White, who became the first athlete since disgraced East German sprinter Katrin Krabbe in 1991 to do the sprint double, had said she took the product for a sleeping sickness, narcolepsy.

White, who ironically had fled the athletes village before the championships claiming she couldn't sleep because it was too noisy, claimed she had not listed it on the medicines she was taking because she didn't take it all the time and that it wasn't on the banned list. However, the IAAF called it into question under the 'related substances' list - whereby it is related to banned substances - and asked her for a further explanation. Bureau Report
