The man made unwanted advances toward them inside the school and both girls were inappropriately touched and sexually assaulted.
The students told staff and police were called.
“I think things obviously escalated and the nature of the assaults were very concerning to the girls, they went beyond just a hug,” said Winnipeg police Const. Jason Michalyshen.
The suspect was arrested on Thursday and charged with two counts of sexual assault. He remains in custody. Police have had contact with the accused in the past and one incident was similar to this one.
