RIO DE JANEIRO: Tensions flared between Olympic champ Mack Horton and China’s Sun Yang in the moments after their tight men’s 400m freestyle final, as the Australian confirmed reports that he had earlier described his rival as a “drug cheat”.

Horton, who defeated London champion Sun on Saturday, confirmed remarks he had made to the Australian Associated Press (AAP) about tensions between the two during training.
“I used the word ‘drug cheats’ because he tested positive,” he told reporters about the report that was published before Saturday’s final.
Sun, sitting next to Horton at the media conference, served a three-month ban in 2014 after testing positive for a banned stimulant. “On the competition stage, every athlete deserves to be respected and there’s no need to use these sort of cheap tricks to affect each other,” he added.
Sun, who broke down in tears while talking to reporters after the race and became red-eyed again after the press conference, has suffered a number of setbacks since he won two gold medals at London 2012. In 2013, he spent a week in jail for crashing a car driven without a license.
