Thomas Bach said Friday it was "chilling" to see how Kamila Valieva's coach treated the Russian teenager after a doping scandal engulfing the skater culminated in an error-strewn performance at the Beijing Olympics. The International Olympic Committee president said he was "very disturbed" to see the 15-year-old fall several times in Thursday's women's figure skating final, as she unravelled and sobbed under the glare of the global spotlight. The World Anti-Doping Agency (WADA) is looking into Valieva's entourage, after the doping controversy tarnished the second week of the Games in the Chinese capital.
