Russian sprinter Anastasiya Kapachinskaya, 200 metres gold medallist at the world indoor athletics championships, has tested positive for a banned steroid, a Russian Olympic Committee official said on Friday.
Nikolai Durmanov, head of the committee's anti-doping division, said the athlete had tested positive for stanozolol, an anabolic steroid.
He said Kapachinskaya's second sample would be tested at the end of April.
"The second test will be carried out at the end of April and after that the question of sanctions will be discussed," Durmanov told Reuters.
Kapachinskaya would almost certainly be stripped of the gold medal she won in the world indoor athletics championships in Budapest last month if the B test proved positive too.
