Former women's hammer world record holder, Gulfia Khanafeyeva, has tested positive for a stimulant, the Russian athletics chief has said.
"We were notified that Khanafeyeva had failed a drugs test at the 2007 World Military Games in Hyderabad, India," president of the Russian athletics federation Valentin Balakhnichyov told Reuters without specifying the substance.
Khanafeyeva, 25, who set a world record of 77.26m in June 2006, became the third high-profile Russian hammer thrower to recently fail drugs tests.
Tatyana Lysenko, who has twice bettered Khanafeyeva's world record but whose mark of 78.61 from May 2007 is awaiting ratification, and European junior champion Yekaterina Khoroshikh have been suspended after testing positive for a hormone blocker the same month.
