The coach of disgraced Belarus shot putter Nadzeya Ostapchuk has confessed he added a banned drug to her food.
It's been revealed overnight the athlete's OIympic gold medal has been handed back to the International Olympic Committee, ready to be given to Kiwi Valerie Adams who placed second at the London Olympics.
Ostapchuk has landed a one-year ban for testing positive for a banned anabolic steroid.
The sentence was lenient because Ostapchuk was completely in the dark that she had doped, according to Alexander Vankhadlo, the head of Belarus' anti-doping agency.
Vankhadlo said that Ostapchuk's coach, Alexander Yefimov, was the only person responsible for the violation of the doping code and was banned for four years.
