Chinese swimmer Chen Xinyi tests positive for a banned substance

BEIJING - Chinese Olympic women's swimmer Chen Xinyi tested positive for a banned substance at the Rio Olympics on Aug. 7, China's official Xinhua news agency said on Friday citing the Chinese swimming association. Doping scandals overshadowed the build-up to Rio and, far from dying down as competition has got under way, have flared anew as US and Australian competitors have branded their Russian and Chinese rivals as drug cheats. -Reuters
