European 100 metres hurdles champion Nevin Yanit has been banned for two years after the Turkish athlete tested positive for banned substances.
Yanit, 26, who won the title in 2010 and 2012, failed a doping test during a competition in Germany in February.
Turkey has been hit by a series of doping scandals at a time when Istanbul is bidding to host the 2020 Olympics, competing against Tokyo and Madrid.
The International Olympic Committee select the host city on September 7.
Earlier this month, the Turkish Athletics Federation gave two-year suspensions to 31 athletes for drug offences, including Esref Apak, who won a silver medal in the hammer at Athens Olympics in 2004.
Russian shot-putter Anna Avdeyeva has also been banned for two years for a drugs offence.
Avdeyeva, 28, tested positive for the banned substance oralturinabol from a sample taken in Moscow on 30 July.
The ban began on 5 August this year and will run until 4 August 2015. (BBC)
