Two former members of the 2010 Olympic security force are being investigated for sexual assault, CTV News has confirmed.

The two alleged assaults happened aboard a cruise ship where out-of-town security force members are residing during the Games.

The suspects are RCMP officers. The alleged victims are also police officers.

The alleged incidents were apparently fuelled by alcohol. While military officers are forbidden from consuming alcohol on the ships, police officers are not.

The Vancouver Police Department is overseeing both investigations.

The two suspects are among seven police officers and four Canadian Forces members who have been relieved of their duties with the 2010 Integrated Security Unit because of improper conduct.

On Friday, RCMP announced that one of those officers is Staff Sgt. Suzanne Denise Martel, a 19-year veteran of the force.

Martel was charged with theft under $5,000 in connection with an alleged shoplifting incident at a Winners store in Burnaby.

None of the others has been charged.
