MOSCOW, January 22. /TASS/. Six-time Olympic short track speed skating champion, Russian national Viktor Ahn has been barred from the 2018 Winter Olympics in South Korea’s PyeongChang, a source familiar with the matter told TASS on Monday.

"Ahn has been barred from participation in the Olympic Games in PyeongChang. His teammates Denis Airapetyan and Vladimir Grigoryev have also been barred," the source said.

Viktor Ahn was born in South Korea’s Seoul as Ahn Hyun-Soo and initially competed for his native country’s team. At the 2006 Winter Olympics in Italy’s Turin he brought South Korea three golds and one bronze medal in short track.
