South Korea's world record-holder Choi Min-jeong seized a convincing victory in the women's 1,500m short track Saturday as she stormed back from her disqualification in the 500m.

Choi, 19, eased to the front with two laps to go and she glided well clear of the field to win in 2min 24.948sec, more than a second faster than China's Li Jinyu.

Kim Boutin of Canada, who received abuse on social media over Choi's disqualification in the 500m final, grabbed her second bronze medal of the Games.

But the agony continued for British world champion Elise Christie, who was stretchered away and taken to hospital after she crashed out painfully in the semi-finals.

Christie was also a crash casualty in the women's 500m final and at Sochi 2014, she went home empty-handed after being penalised in all three of her events.
