Three people are facing charges in connection with a series of beatings at or near Sir Wilfred Laurier Collegiate in Scarborough.
Police say it appears the attacks are happening so the fights can be recorded and posted to Snapchat and Instagram.
Some students call the disturbing trend “Friday Night Fights.”
The incidents were first reported to police Friday, after one student was jumped by a group of 6, while others filmed it.
The Toronto District School Board says the school and the board are aware of the recent fights and are working closely with police to offer any assistance they can.
The three teens have been charged with assault causing bodily harm.
