Olympic gold medal judoka Naidan Tuvshinbayar has been arrested over an assault that reportedly left the victim with severe brain injuries. Tuvshinbayar, the president of the Mongolian National Olympic Committee and that country's first ever Olympic gold medalist, was questioned by police Saturday in connection with an assault of fellow judoka Erdenebileg Enkhbat, which left Enkhbat in intensive care at the hospital according to Mongolian media.

Tuvshinbayar, who won the 100 kg division at the 2008 games and was a silver medalist in 2012, was taken into custody Monday and will serve 20 days in jail. He was elected unopposed as president of the Mongolian Olympic Committee last August.
