FINA comes to defence of Chinese swimmer, saying 'no factual basis' to doping questions

LONDON - The governing body of swimming has come to the defence of Chinese star Ye Shiwen, saying there is "no factual basis" to speculation about possible doping.

FINA felt compelled to issue a statement Wednesday about Ye, a double gold medallist at the London Games.

After the 16-year-old Ye broke the world record in the 400-metre individual medley, the head of an American coaching organization questioned her legitimacy. Ye was peppered with more questions after her victory in the 200 IM and denied that she had ever used banned substances, saying her success was due to hard work.

FINA says Ye has been tested four times in the past year, including twice before her country's Olympic trials this year.
