Simone Biles hits out at hackers

Simone Biles has defended her right to use medication to tackle her ADHD and denied any suggestion it gave her unfair advantage.

The American teenager who won four Gold medals at the Rio Olympic games, reacted after a group of hackers claimed to have found files showing and the Williams sisters were allowed to take banned substances by anti doping bosses.

 Biles tweeted: 'Having ADHD, and taking medicine for it is nothing to be ashamed of nothing that I'm afraid to let people know.'

On Tuesday, private medical data of top athletes including Simone Biles, Serena and Venus Williams were hacked and posted online.

The records which includes Therapeutic Use Exemptions (TUEs), which allow athletes to use otherwise-banned substances because of verified medical need.

Biles further tweeted: 'I have ADHD and have taken medicine for it since I was a kid. Please know, I believe in clean sport, have always followed the rules, and will continue to do so as fair play is critical to sport and is important to me.'

  

The World Anti-Doping Agency (WADA) said last night the Russian-based Fancy Bears group had leaked another batch of confidential athletes' information from its database.

WADA said the leak contained confidential data of 25 athletes from eight countries.

It said the targeted athletes included 10 from the United States, five from Germany, five from Britain, and one each from Czech Republic, Denmark, Poland, Romania and Russia. It did not identify the athletes.

WADA said the Russian group had again illegally gained access to its Anti-Doping Administration and Management System.
