Asli Cakir Alptekin,the winner of Olympic gold at London 2012 who has been stripped of the title, is banned for life by the Turkish Athletics Federation for a third doping offense.

 Alptekin won the 1500 metres title in London, a race where six of the first nine finishers have served drugs bans before or since, leading some to refer to it as the “dirtiest race in history”.

The 32-year-old was stripped of both her Olympic and European 1500m titles in 2015 and received an eight-year ban for anomalies in her biological passport.

She returned to the track this year, however, after the ban was halved and its start date backdated to 2013. She finished 11th in the European Champion Clubs Cup Cross Country event in Portugal in February.

“Asli Cakir, who wrote history by winning a gold medal in the 2012 London Olympics, has received her third punishment for doping,”

“We will never ever give ground to those who become involved in doping. Everyone should know this,” Turkish Athletics Federation Chairman Fatih Cintimar.

The nature of her latest offense has not been made public.
