Russian hammer thrower Tatyana Lysenko has been stripped of the gold medal she won at the London 2012 Olympics following a positive drugs retest.
The double world champion, who was already serving a doping ban imposed by athletics’ governing body the IAAF, now faces a lifetime ban from the sport.
“Re-analysis resulted in a positive test for the prohibited substance turinabol,” a statement from the International Olympic Committee reads.
Lysenko has now tested positive for drugs three times during her 15-year career, missing the 2007 World Championships and 2008 Olympic Games through suspension.
London 2012 silver medalist Anita Wlodarczyk of Poland is expected to be promoted to gold as a result of the Russian’s latest offence.
