Canadian figure skater Nikolaj Sorensen was suspended Wednesday for at least six years for sexual maltreatment, the Office of the Sport Integrity Commissioner announced.

The suspension was listed on the office’s abuse-free sport registry and is subject to challenge or appeal.

Skate Canada, the country’s governing body of figure skating, said in a statement it “has been made aware of the decision from Abuse-Free Sport in this matter and is taking the necessary action to comply with it.”
