An investigator supported the World Anti-Doping Agency's actions in a doping case concerning 23 Chinese swimmers. The investigation revealed doubts expressed by WADA's science director regarding China's explanation of how the athletes were exposed to contamination.
WADA released an interim report from the Swiss prosecutor, Eric Cottier, who found no evidence of favoritism towards China in the case. Cottier deemed WADA's decision to trust Chinese authorities, who claimed the swimmers ingested a banned heart medication, as reasonable.
