The Royal Canadian Mounted Police said the latest suspect, a 14-year-old boy, was arrested Saturday and charge with aggravated sexual assault, aggravated assault and unlawful confinement, the Canadian Broadcasting Corp. reported.
The attack allegedly occurred in Prince George, British Columbia, last week. The boy was found unconscious in a snow bank near an apartment building. Police said it appeared a group of youths, ages 15 to 20, enticed the boy into the building where he was physically and sexually assaulted.
Another boy also was physically assaulted by some members of the group during the incident, police said.
The other six suspects include four minors and two adults, the CBC said.
