A number of pupils have been affected over a number of years by the alleged “serious misconduct” of Viotti. “We have confirmed that there have been several boys who have been affected over a number of years,” school principal Guy Pearson said.

Pearson said the school was doing everything it could to ensure the mental well-being of pupils, staff, and others affected by the “very sad events”. He appealed for respect of the dignity and privacy of the people affected, while the investigation continued. The school has also made psychologists, employed by the Bishops Support Unit, as well as external clinical psychologists and psychiatrists available to any boy or family member that may have been affected by the events. Viotti is the daughter of Dave Mallett, who is a history teacher at the school and coaches the first rugby team. Viotti, who married long-term boyfriend Pavo Viotti in September last year, was reportedly a water polo star as a teenager and was one of the “Beauties of Sport” featured in Sports Illustrated magazine in 2009. The couple has reportedly separated. An explicit video of a nude woman on a bed has been loaded on to a well-known, free pornographic website citing the name of Fiona Viotti, 30, the Bishops Diocesan College water polo coach who resigned last week amid allegations of a sexual affair with a matric pupil.

Various explicit videos and pictures of a woman many claim to be Viotti have been doing the rounds on social media and WhatsApp since the story broke last week.

On Thursday, William Booth, Viotti’s attorney, said he would be taking steps to have the video removed from the website as it was posted without her permission.

Viotti left Bishops with immediate effect last week.
