The confidential health records of Chorley cyclist Sir Bradley Wiggins have been leaked online by hackers.

The World Anti-Doping Agency (Wada) said the "criminal attack" by a Russia-based cyber-espionage group had released a second tranche of documents, including details of American and German athletes.

Wada first fell victim to the hackers on Tuesday when medical records relating to "therapeutic use exemptions" granted to certain athletes were made public.

The body confirmed on Thursday that another leak of "confidential athlete data" had taken place - although it did not identify the athletes affected.

There is no suggestion that any of them have done anything wrong.
