Belarusian champion caught using doping

A Belarusian Katsiaryna Artsiukh won the 400 meters distance at the obstacle race at the junior championship a month ago. Now, according to "Pressball", it became known that her doping test-A, taken right after the tournament, showed a positive result.
It is unclear yet whether the champion and her coach Kanstantsin Cvierdakhleb will insist on disclamation of the test-B. However, they claim they are not guilty.
