Six students from a prestigious private all-boys Catholic school in Toronto were arrested on Monday and charged with sexual assault relating to a video that was posted online.
Insp. Domenic Sinopoli said Tuesday, that one of the videos was being investigated as a "threatening occurrence" and the other as a case of "assault with a weapon".
Sinopoli added police have reason to believe there are more victims and videos out there, and urged anyone who has not already come forward to contact them.
In one video, Sinopoli says a person is being assaulted with a belt.
"We're going to have to look for as well is leadership from all fronts - from parents, from the administration of the school and from the community and the police and others - to make sure that we learn from this and that justice is served", he said at city hall. "Up until now the school has been fully cooperating".

A video of that incident was first obtained by school administrators on November 12.
The school's principal, Greg Reeves, defended his decision to tell police about the sexual assault two days after he found about it. CP24 has learned the date of the incident was November 7, 2018.
"Sometimes students may be a little reluctant to come to police", he said, noting if witnesses can't "muster the energy or the courage" to come forward then they can do so through the school or Crime Stoppers. Sinopoli said it was his view that the school had missed him in their own internal investigation that led to the expulsions.
Administrators also obtained another video on Monday, showing an alleged assault.
"The individual who was arrested (on his way to school), it is my belief that the school did not appreciate his involvement", Sinopoli said. They are facing multiple criminal charges including assault, gang sexual assault and assault with a weapon.
They were held in custody until being released on bail later Monday.More news: Struggling Oilers fire head coach Todd McLellan, replace him with Ken Hitchcock
None of the allegations has been tested in court.
St. Michael's College principal Gregory Reeves said: "These incidents are clearly indicative we have a problem".
Instead, the school said, students will spend that time in regular classes as well as "workshops and discussions pertaining to the issues that have arisen".
The school says it also cancelling all extracurricular activities and sports teams for the remainder of 2018, "with the goal of returning to all such events in 2019".
Speaking to reporters on Tuesday, Toronto Mayor John Tory said the culture at the school may need to change.
"I would hope that in every public school, every private school, . every community organization, people are taking bad stories like that and using it as a moment to reflect".More news: More than 50 killed in blast at religious gathering in Kabul
