Chinese swimming authorities have launched an investigation into cyberbullying of diving star Quan Hongchan, a three-time Olympic gold medallist. The investigation has been reported to the police. Quan, who won her first gold at Tokyo 2020 and two more at the next Paris 2024 games, has spoken about online commentary over her weight and the pressure she feels to diet. China's Swimming Management Centre has issued a statement condemning malicious acts that harm athletes' physical and mental health and promising to improve systems for the athlete protection.
