Greek hurdler tests positive for banned drug - 2008 Olympics - SI.com:
"Halkia was tested a few days before the Beijing Olympics in Japan, where
Greece's track and field team had been training. She said she had volunteered to
take part in WADA's pilot program in which athletes submit themselves
voluntarily to regular testing.
Halkia, who has moved out of the Olympic
Village, said she was sorry she could not take part in the games and that she
had expected to make the 400-meter hurdles final."
