Cpl. Derrick Gallagher of Petawawa, Ont., is facing seven new criminal charges in a sexual assault investigation that now involves 16 confirmed victims, and possibly others.

The seven new charges include:

  • One count of sexual assault.
  • One count of breaking and entering.
  • Five counts of voyeurism.

Gallagher was initially arrested on March 31, and was charged with eight counts of sexual assault and two counts of voyeurism in relation to alleged incidents dating back to 2007.

An Ontario Provincial Police investigation had begun March 29 after a woman complained to them, police said. That week, their evidence led them to eight alleged victims in the town of Petawawa.

In April, Gallagher was charged with eight more counts of sexual assault, nine more counts of voyeurism and one count of assault.

Gallagher is now facing a total of 35 charges.

The 31-year-old infantryman with the 1st Battalion Royal Canadian Regiment joined the military in December 2005, and served in Afghanistan from September 2008 to April 2009.​

OPP have said there could be other victims who may have been drugged and may not know they were assaulted.

Police are asking anyone else with information to contact them at 613-735-0188.
