LIMA (Reuters) - A first batch of athletes suspected of having been part of a Russian doping ring at the Sochi 2014 Winter Olympics may soon be charged with doping-related offences, the head of the investigation said on Friday.

IOC member Denis Oswald said evidence gathered so far will be combined with results of tests to determine whether urine and blood sample bottles had been tampered with, to replace positive samples with clean samples.
