The World Anti-Doping Agency confirmed on Thursday it was looking into a leak about an investigation that resulted in the agency clearing 23 Chinese swimmers who tested positive for a banned heart medication before the Tokyo Olympics in 2021.

The agency has defended its decision to clear the swimmers of doping. It said it had agreed with Chinese anti-doping authorities who found the swimmers’ samples were contaminated.

The existence of the investigation by China and Wada had been kept under wraps before the New York Times and German broadcaster ARD reported on it last year.

ARD reported on Wednesday that the agency was looking for the person who tipped off the news media about the investigation. The move is unusual because Wada encourages and relies on whistle-blowers to root out doping.
