Brett Sutton, a convicted child sex offender and coach of Swiss triathlon silver medallist Julie Derron, has left the Paris 2024 Games following an investigation by the International Olympic Committee (IOC). Sutton was granted accreditation by the Chinese National Olympic Committee, despite a history of sexual abuse offenses, including a 1999 guilty plea for abusing a 13-year-old swimmer. The IOC confirmed Sutton's departure and emphasized that accreditation for coaches is the responsibility of national committees. The situation has raised broader concerns about allowing individuals with past convictions for sexual offenses to attend the Olympics, especially in light of another case involving Dutch beach volleyball player Steven van de Velde. The IOC is set to review its safeguarding measures in light of these incidents. Both Sutton and Van de Velde's cases have sparked discussions about the vetting processes for coaches and athletes at the Games.
