Council director General Husain al Musallam said in a statement on Tuesday that the banned stimulant sibutramine was found in a urine sample taken from Tai Cheau Xuen after competition on Sept. 20.
He said Tai was disqualified and stripped of her gold medal in the nanquan martial arts style category and bronze in the nandao category. It wasn't immediately clear whether Tai was still in Incheon.
The test findings were to be forwarded to the Asian and international wushu federations and the World Anti-Doping Agency for further action, including a possible competition ban.
