Almost 500 drug test samples from the 2006 Winter games in Turin have been re-examined, the International Olympic Committee said on Wednesday, without giving details on possible positive tests.
The IOC said that 489 of the overall 1,219 samples gathered at the Games were tested by the laboratory in Lausanne, Switzerland, using new and improved methods to detect substance abuse.
The IOC said it "cannot and will not issue further comments with regard to this process, nor will it answer questions, at this point in time. Further communications will be issued in due course."
Athletes have been caught cheating in re-tests of samples from other Olympics. Samples can be stored and re-tested for 10 years after Olympic Games under updated rules by the World Anti-Doping Agency, instead of eight years as in the past.
