South Korean Olympic speed skating champion Lee Seung-hoon is facing allegations that he assaulted two teammates on multiple occasions.

In announcing the findings of its probe into the Korea Skating Union on Wednesday, the sports ministry said, without naming names, that a skater is believed to have struck two younger teammates during overseas competitions in 2011, 2013 and 2016.

Later, speed skating sources said the accused athlete is Lee, a two-time Olympic gold medalist. According to one source, Lee said he was just playing around with his teammates and hit them lightly, but his teammates feel that they were assaulted with malicious intent on Lee's part.
