The head of Germany's Olympic body says one of the country's top biathletes is on her way home after testing positive for a banned stimulant.

Michael Vesper, chief of German Olympic body DOSB, said during a brief news conference Friday night that former two-time Olympic gold medalist Evi Sachenbacher-Stehle was removed from the team after testing positive in two samples. She blames the test on a nutritional supplement, saying she never knowingly took performance-enhancing drugs.

Vesper told reporters the news rocked the German Olympic team.

"Of course we were shocked by the news and the mood in our Olympic team was clearly very bad. We are absolutely in favor of team sport and against any kind of manipulation," he said. "This is why — before the games and during the games — we took action. We also acted quickly and decisively now in accordance with the athletes' agreement, an agreement that we have concluded with Evi Sachenbacher-Stehle."
