UK Anti-Doping (UKAD) has condemned hackers for leaking the medical records of athletes, citing "unnecessary and unwarranted worry".
Olympic gold medallists Laura Trott and Nicola Adams became the latest British athletes to have private information released into the public domain when they featured in the third batch of names whose 'therapeutic use exemptions' (TUEs), held on file by the World Anti-Doping Agency (WADA), were released by cyber espionage group 'Fancy Bears'.
TUEs can be issued to athletes who have an illness or condition which requires the use of medication which is on WADA's prohibited list.
Trott and Adams were joined on the list by swimmer Siobhan-Marie O'Connor and rower Olivia Carnegie-Brown, who both won silver for Team GB at Rio 2016.
There is no suggestion of any wrongdoing by any of the athletes.
UKAD chief executive Nicole Sapstead said: "We absolutely condemn the latest release of personal information pertaining to members of Team GB.
"It is causing unnecessary and unwarranted worry for the athletes affected. We continue to treat this matter with the utmost concern and seriousness, and we are in close contact with WADA."
A WADA statement read: "Stakeholders should know that WADA is being consulted and taking action based on intelligence and advice from the very highest levels of international law enforcement."

Adams started aggressively against her experienced opponent, repelling Hansen's advances and taking it clearly on the scorecard.
