Chinese officials say a female Chinese swimmer has tested positive for a banned substance at the Rio Olympics — the first competitor in the sport to fail a test at the games.
The Chinese Swimming Association says 18-year-old Chen Xinyi has tested positive for the diuretic hydrochlorothiazide after she finished fourth in the women's 100-meter butterfly Sunday, missing a bronze medal by nine-hundredths of a second. Xinhua, China's official state news agency, reported the story Friday.
