World bodies vow action following leak of 'suspicious' blood tests by top athletes

Both the World Anti-Doping Agency and the International Association of Athletics Federations have promised to act if information contained within the ”biggest leak of blood-test data in sporting history” proves to be correct.

The Sunday Times along with the German broadcaster ARD/WDR, has had access to a database containing more than 12,000 blood tests from 5,000 athletes and which it claims reveals ”the extraordinary extent of cheating by athletes at the world’s most prestigious events”.
