IOC disqualifies Beresnyeva from London 2012 Olympics

Ukrainian swimmer Olga Beresnyeva has been stripped of her seventh place finish at the London 2012 Olympic Games after a retrospective drug analysis tested positive for recombinant erythropoietin (rEPO).

An International Olympic Committee (IOC) investigation conducted further analyses of urine samples taken during London 2012.
“These additional analyses were performed with improved analytical methods in order to detect prohibited substances which could not be identified with the analyses performed at the time,” stated the IOC.
Beresnyeva “accepts full responsibility” for her “fatal mistake”. She admitted to taking the banned substance when her results started declining and she did not want to miss her “last chance” to compete in the Olympics. She bought the product online and insists that for the rest of her career she had “always [kept] straight”.
An IOC disciplinary commission ruled that Beresnyeva must be disqualified from the women’s 10km open water marathon event, excluded from the 2012 Games and have her diploma from the event withdrawn. After modifying the results of the event, FINA will then consider any further sanctions against Beresnyeva.
