Athletics looks set to be plunged into a new doping crisis after IAAF test data leaked to two news organisations showed hundreds of suspect samples from athletes, including Olympic and world championship medallists, the BBC reported on Sunday.
Britain's Sunday Times newspaper and German broadcaster ARD/WRD say they had been given access to the results of 12,359 blood tests given by more than 5,000 athletes over 11 years.
When analysed by scientists, the tests showed more than 800 athletes had given blood samples that were "highly suggestive" of doping or "abnormal", reported the BBC, who added they had also seen the documents.
Although abnormal blood tests are not in themselves proof of doping, the release of the data will be an embarrassment to the International Association of Athletics Federations (IAAF) less than a month before its world championships in Beijing.
