British cycling stars Bradley Wiggins and Chris Froome are among the latest batch of athletes to have their confidential medical information released by a group of Russian hackers.
The hacking group Fancy Bears published the names and documentation of 25 athletes that it alleged had taken banned substances.
"We go on exposing the athletes who violate the principles of fair play by taking doping substances," the group said in a new entry, called WADA databases Part 2, on its website. It went on to promise new leaks.
The documents released, however, appeared to be related to "therapeutic use exemptions" (TUE) obtained by the athletes from various sporting bodies. TUEs allow competitors to take drugs in order to treat medical conditions; there is no suggestion of wrongdoing by the athletes.
This follows the release on Tuesday by the same hackers of TUEs belonging to celebrated U.S. gymnast Simone Biles, basketball player Elena Delle Donne and tennis superstars Serena and Venus Williams.
The World Anti-Doping Agency (WADA), which has previously revealed that the confidential information was stolen during a hack of its database, confirmed on Thusday that there had been another batch of information leaked by Fancy Bear, involving 10 U.S. athletes, 5 Germans, 5 Brits, and one each from the Czech Republic, Denmark, Poland, Romania and Russia.
