The Russian sports minister says no one will face criminal charges over the worst doping scandal in the country's history.
A report in November by a World Anti-Doping Agency (WADA) commission alleged systematic, state-sponsored drug use in Russian track and field and a widespread cover-up of doping.
The former head of the Russian track federation was also accused of a role in extorting 450,000 euros ($A682,000) from a marathon runner and was later banned for life from global track and field.
Sports minister Vitaly Mutko has told Russian sports portal Sportfakt that prosecutors "carefully examined the report in question and did not find a single legally supported fact to open any kind of case".
The WADA report led to Russia being suspended from all international track and field, including the Olympics.
