In a first for any Olympic Games, centers to address incidents of sexual misconduct were opened over the course of the 16-day sporting event as a way for athletes, volunteers, spectators and anyone else to come forward for help.

During the PyeongChang Winter Olympics, the four centers reported at least 10 cases — classified as “sexual harassment” — before Sunday’s closing ceremony, a director said.

Officials with the Gender Equality Support Centers, however, declined to comment on the types of people who reported the incidents and what generally occurred, citing confidentiality reasons, but said that none of the victims ultimately asked for police intervention.

The center’s counselors were able to notify appropriate supervisors about cases in which the actions of a person accused of misconduct might warrant their removal from a venue or dormitory, for instance.
