A captain and a sergeant at New Brunswick's Gagetown military base have been charged with sexual offences. 

The Canadian Forces National Investigation Service says the charge against Captain Simon Duval relates to an alleged sexual assault at the 5th Canadian Division Support Base near Oromocto in December 2010 or January 2011. It says the victim is also a member of the Canadian Armed Forces.

Sgt. Brent Douglas Hansen, who works at range control, was also charged on Wednesday with two counts under the National Defence Act related to allegedly accessing child pornography while on duty at the base between June 26, 2014, and Sept. 22, 2014.

No dates for a court martial in either case have been set, according to officials.

The Canadian Forces National Investigation Service is a unit of the independent Canadian Forces Military Police Group whose mandate is to investigate serious and sensitive matters in relation to Department of National Defence property, Department of National Defence employees and Canadian Armed Forces personnel serving in Canada and around the world.
