With news surfacing today that Gamze Bulut, a Turkish athlete who finished second in the women’s 1,500m at the 2012 Olympics, failed a drug test, another athlete from the London Games has been busted.

Just days ago, Abeba Aregawi, the fifth place finisher at the London Olympics and world champion in 2013 over the same distance, tested positive for a banned substance and is currently suspended.

The German channel, ARD, will be airing a documentary tonight entitled Doping Top Secret: Russia‚Äôs Red Herrings, which is expected to further expose Russia’s lack of doping enforcement.

In addition to the two most recent cases, Aregawi and Bulut, other athletes from the race, including the winner, have been linked to performance-enhancing drugs following the Games. Below are details on the top-10 (in order of placement).

Two Canadians, Hilary Stellingwerff and Nicole Sifuentes, made the semi-final of the event but missed out on qualifying for the finals. Stellingwerff was one spot removed from making the final in heat one (fifth in the heat) while Sifuentes was 10th in heat two. Both would be in the top-12 if athletes linked to PEDs were eliminated.

Asli Cakir Alptekin – Stripped of her gold medal and serving an eight-year ban, Alptekin has been stripped of all her results dating back to July 29, 2010.
