Four Hamilton high school students have been arrested after another student was assaulted earlier this month.
Police say they responded on Jan. 16 to a ``large disturbance'' near Bishop Tonnos Catholic Secondary School involving students from that school and St. Thomas More school.
They say a 15-year-old from Bishop Tonnos was assaulted and received minor injuries, and the incident was captured on video.
Investigators say roughly 20 students from St. Thomas More were present.
Four teen boys, three 15-year-olds and a 14-year-old, were arrested between last Tuesday and Saturday.
Police say the teens, who cannot be identified due to their age, have been referred to a diversion program related to assaults.
