2012 Olympic champion stripped of women's 1,500-meter title for doping

Olympic champion Asli Cakir Alptekin of Turkey has agreed to surrender her 1,500-meter Olympic gold medal and serve an eight-year ban for blood doping, the IAAF and CAS announced on Monday. 

The eight-year ban was reached on a settlement by the International Association of Athletics Federation and the Court of Arbitration for Sport. The Turkish Athletics Federation cleared Alptekin of any doping charges in 2013. The IAAF found irregularities in her biological passport, which monitors doping over time, and appealed to the CAS. 

This is Alptekin's second positive test after she served a two-year ban for anabolic steroids while competing as a junior athlete at the 2004 World Junior Championships. The eight-year ban is a maximum punishment for a second offense.
