LONDON: Turkey’s Asli Cakir Alptekin, who came back from a doping ban to win the women’s 1,500 meters under a cloud of suspicion at the 2012 Olympics, faces a lifetime ban after being charged with another anti-doping offense, athletics officials said yesterday.

Cakir, who was given a two-year ban in 2004 after a positive dope test at the world junior championships, finished at the London Games ahead of compatriot Gamze Bulut, who had improved her personal best by 18 seconds in the previous year.

Cakir was charged on the basis of abnormal blood values from her biological passport.

Another Turkish athlete, double European 100m hurdles champion Nevin Yanit, also faces a ban after “multiple positive findings in both in-competition and out-of-competiton tests,” the International Association of Athletics Federations said.

Both athletes have been charged with anti-doping rule violations by the IAAF and are provisionally suspended.

Their cases have been referred to the Turkish federation for adjudication and Cakir faces an automatic life ban for a second doping offense.

The burly Cakir’s ban will hardly raise eyebrows in the world of athletics, despite her denying the use of performance-enhancing drugs when grilled immediately after her London success.
