The World Anti-Doping Agency allowed US tennis players Serena and Venus Williams to take banned substances, while gymnast Simone Biles failed a doping test yet avoided disqualification, a hacking group revealed Tuesday.
According to the Fancy Bear group, which released Wada documents after hacking the agency, former No. 1 tennis player Serena Williams was allowed to take banned substances such as oxycodone, hydromorphone, prednisone and methylprednisolone in 2010, 2014 and 2015.
Venus Williams was allowed to take prednisone, prednisolone and triamcinolone among others in 2010, 2011, 2012 and 2013. The documents do not reveal the diagnoses of the athletes which led to Wada allowing them to take the substances.
WADA confirmed on Tuesday that the group had been able to access athlete data, including confidential medical reports, related to the Rio Olympics and subsequently released it into the public domain.
“WADA deeply regrets this situation and is very conscious of the threat that it represents to athletes whose confidential information has been divulged through this criminal act,” said WADA’s director general Olivier Niggli.
