The Canadian Forces National Investigation Service charged former NHL player Dave “Tiger” Williams with sexual assault on Wednesday.

According to the NIS, the charges are related to reported incidents during a Canadian Armed Forces flight to Latvia in December for a “sanctioned morale visit” to armed forces personnel overseas. Williams, 64, faces one count of sexual assault and one count of assault against a passenger on that flight.

The Canadian Forces NIS has jurisdiction over incidents that occur on Canadian military bases and during deployment.

“Every allegation of sexual assault is taken seriously by the Canadian Forces National Investigation Service. In all cases, no matter who the accused is, we strive to restore the dignity of victims by fully investigating their complaints, gathering evidence, reconstructing events, and if warranted, laying appropriate charges,” Lt. Col. Kevin Cadman, Commanding Officer for the Canadian Forces NIS, said in a statement.

Popular former NHL player Dave “Tiger” Williams has been charged with sexual assault and assault after an incident on a military flight during a pre-Christmas trip to visit Canadian troops in Latvia, according to multiple reports.

Williams, 64, was charged Thursday by the Canadian Forces National Investigation Service with two counts of sexual assault and assault under the Criminal Code after an alleged attack on board the military flight in December, GlobalNews.ca reported.

There are conflicting reports over whether the alleged victim was a fellow passenger or an attendant on the flight.

According to reports, although the charges were filed by Canadian military police, Williams’ case will be processed in the civilian court system in Ottawa, though no court date for his first appearance had been set as of mid-day Friday.

Williams was taking part in a holiday visit to Canadian troops that are part of a NATO operation in Latvia in Eastern Europe.

A fan favorite with the Maple Leafs from 1974-80, Williams’ NHL career, which ended in 1988, also included stints with the Canucks, Kings and Whalers.
