Caroll said it was "of concern" and the school would be working to warn the school and community.
He said they would be putting in extra measures to be mindful of where students were at all times while at school and would be in talks with police.
The police spokeswoman said they actively encouraged people to tell children and young adults to report anything that made them feel unsafe or uncomfortable.
She said they would like to remind families to have discussions around behaviours and actions that are inappropriate or that make a child feel uncomfortable.
