PYEONGCHANG, Korea, Republic Of -- Short-track speedskater Kim Boutin was the target of nasty messages and even death threats on social media after she was awarded the bronze medal when a South Korean was disqualified in the 500-metre race at the Pyeongchang Olympics.

Boutin finished fourth, but was promoted to third when Minjeong Choi was disqualified for interfering with the Canadian. The ruling by officials didn't sit well with South Korean fans.

Radio-Canada reported that thousands of angry messages and some death threats were directed at Boutin.

"Congratulations on a dirty medal," one message said.

"You had been teaching Kim Boutin how to cheat, Canada!!" said another on Twitter.

Boutin, from Sherbrooke, Que., closed her social media accounts and the RCMP, the IOC and Speed Skating Canada were looking into the matter.

"The health, safety and security of all our team members is our top priority and as such we are working closely with Speed Skating Canada, our security personnel and the RCMP," said a statement from the Canadian Olympic Committee. "We will not make further comment on this issue, so that Kim can focus on her upcoming events."
