During the competitive swimming portion of the 2016 Olympic Games, we reported how China’s top 100 butterflier, Chen Xinyi, had failed a doping control test before heading to Rio de Janeiro to compete. The swimmer reportedly tested positive for the substance hydrochlorothiazide, a diuretic which is sometimes used as a masking agent.
Chen was reportedly informed of the positive test on Tuesday, August 9th and the swimmer subsequently appealed the case to the Court of Arbitration for Sport (CAS). Chen finished 4th in the 100 butterfly, missing the bronze medal by just .09 seconds. She was later absent from the women’s 50m freestyle heats and off of her nation’s 4x100m medley relay.
With Chen’s B sample also having been confirmed of testing positive for hydrochlorothiazide, the CAS upheld the decision and expelled Chen from the Rio Olympics. Now, the Chinese Swimming Association has declared it will be launching a ‘thorough investigation’ into the positive doping result.
“The Chinese Olympic delegation has demanded the Chinese swimming body to start a full investigation into the matter in order to clarify the facts and seek out the truth,” said the delegation in a statement sent to Xinhua News Agency.
“The delegation will punish those responsible in accordance with the truth and law.”
CAS says it is now in FINA’s hands to determine the athlete’s punishment following the conclusion of the Games.
