Ottawa police have charged a 27-year-old gymnastics coach with sexual assault in relation to incidents alleged to have occurred in the last two months.

Klyne Pitpitunge was charged Sunday with sexual assault and sexual interference, which involves sexually touching a person under the age of 16.

Police said Tuesday the alleged victims are between five and 10 years old, and investigators are concerned there could be more victims between four and 12 years old.

Pitpitunge worked at a gym on Morrison Drive west of Greenbank Road, according to police.

In a statement on its Facebook page, Starr Gymnastics said Pitpitunge, who was known as "Wookie," was hired in March and that his employment has been terminated.

The club said it's conducting its own investigation into the matter, and would not comment further.
