American Marconi Wireless News - Russian skater Valieva tested positive for banned drug: Olympic testers

The case will be decided by the Court of Arbitration for Sport before February 15, when the 15-year-old is scheduled to take part in the individual event at the Olympics, the International Testing Agency (ITA) said in a statement.

It is just the latest doping scandal surrounding Russian athletes in recent years at Olympic Games.

Valieva tested positive for trimetazidine, a metabolic agent that is prescribed for the treatment of angina and vertigo.

It is banned by the World Anti-Doping Agency because it can increase blood flow efficiency and help endurance.

The ITA said Valieva submitted a sample during the Russian championships on December 25 but the positive test was not confirmed by an internationally accredited laboratory until February 8

By that time she had already taken part in the team skating competition at the Beijing Games and helped Russia to win after becoming the first woman in history to produce a quadruple jump at an Olympics.

Once the Russian anti-doping agency (RUSADA) received the result, it provisionally suspended the teenager, a decision which would have ruled her out of the rest of the Olympics.

Valieva successfully challenged that decision and the ban was lifted on February 9. She was seen training in the Chinese capital on Friday.

Now the International Olympic Committee says it will challenge the decision to lift her suspension.

"Under the World Anti-Doping Code, the World Anti-Doping Agency (WADA), the International Skating Union (ISU), RUSADA and the IOC have a right to appeal the decision to lift the provisional suspension before the Court of Arbitration for Sport (CAS). The IOC will exercise its right to appeal," the ITA said in a statement.

The confirmation that she failed a doping test explains why the medals ceremony for the figure skating team event has not taken place.

Russian competitors are taking part in Beijing as the Russian Olympic Committee (ROC) after the nation was banned because of a massive state-sponsored doping scheme at the 2014 Sochi Olympics.

IOC spokesman Mark Adams said in Beijing: "We want to expedite this as quickly as possible.

"It's very important for everyone involved, not least the 15-year-old athlete that is concerned, that we have due process, that it's seen to be done properly and that people can have confidence in the decisions that are taken.

"We are working as fast as we can under the circumstances to get that.

"Such cases are not helpful to the Games."
