A Spanish figure skater is the fourth Winter Olympics athlete to fail her doping test

• Spanish figure skater Laura Barquero tested positive for clostebol, a banned substance, the ITA said.
• Barquero is the fourth athlete to fail a doping test during the Winter Olympics in Beijing.

Two days after the Winter Olympics in Beijing ended, Spanish pair skater Laura Barquero has become the latest athlete to fail a doping test.

The 20-year-old tested positive for clostebol, a banned substance, the International Testing Agency (ITA) said in a statement on Tuesday. Clostebol is a synthetic steroid that enhances physical performance.

According to the statement, the Court of Arbitration for Sport will be hearing Barquero's case. The Spanish Olympic Committee had originally been notified of an athlete's positive doping test, but Barquero was not named, per the Associated Press.

The sample was collected after the pair's short program on February 18, according to the ITA's statement.

Barquero and her partner Marco Zandron placed 11th in the pairs event in their first participation in a Winter Games.

In addition to Barquero's case, three athletes had already failed doping tests during the Games. Ukrainian cross-country skier Valentyna Kaminska and bobsledder Lidiia Hunko, and Iranian alpine skier Hossein Saveh Shamshaki had also tested positive for banned substances.

The Games was marred by teenage figure skater Kamila Valieva's doping controversy, as she was allowed to compete in the singles skating event despite testing positive for a banned substance — the heart medication trimetazidine — at the Russian national championships in December. Valieva blamed the failed drug test on a mix-up with her grandfather's medication.
