GENEVA, October 11. /TASS/. The International Olympic Committee on Tuesday announced that Russian athlete Tatiana Lysenko has been disqualified from the 2012 Olympic Games in London 2012, in which she won the gold medal.
Lysenko, 33, who won gold in the women’s hammer throw event will have to return the medal to the IOC, the committee said in a statement.
"Re-analysis of Lysenko’s samples from London 2012 resulted in a positive test for the prohibited substance dehydrochlormethyltestosterone (turinabol)," the IOC said.
"The Russian Olympic Committee shall ensure full implementation of this decision," the IOC said adding that the additional analyses of samples collected during the 2008 and 2012 Olympic Games in Beijing and London were performed with improved analytical methods, which were not used during the competitions.
