International Olympic Committee spokesperson Mark Adams says reports of athletes testing positive for banned substances must be handled in a "proper, transparent way, a legal way". "We ask for the patience and understanding of all the athletes involved here," he adds. At present, a date cannot be set for the postponed medal ceremony for the figure skating team event. Russian media reported that 15-year-old figure skating star Kamila Valieva, who led Russia to team gold at the Beijing Olympics this week, tested positive for a banned heart medication before the Games.
