Chinese swimmer Sun Yang yelled at a rival competitor as they stood on the podium Tuesday, then confronted the same competitor as they walked away.
Sun, who had just won the 200-meter freestyle event at the 2019 World Aquatics Championships in South Korea, appeared to be upset that British swimmer (and co-bronze medalist) Duncan Scott refused to shake his hand or pose for pictures with him.
As they left the podium, Sun doubled back, got in Scott's face and appeared to be saying "I win, I win, you lose" as they exited the area, according to The Sydney Morning Herald.
