Mariya Savinova is the latest in a growing list of Russian athletes to have past Olympic Medals taken away over the doping scandal.
Savinova, has been stripped of her 800-meter Olympic Gold medal, which she won at the 2012 London Games. What’s more, she was also banned for four years by the Court of Arbitration for Sport.
Cas said the 31-year-old was "found to have been engaged in using doping" from July 2010 until August 2013.
This means that she will also lose her 800 meter Gold from the 2011 World Championships and the European Championships in 2010.
