A student is in hospital with head injuries after a violent incident at a Guelph high school.

Witnesses told authorities that a 15-year-old student was punched and kicked in the head by two other students during a fight at College Heights Secondary School.

Those other students, a 15- and 16-year-old, are now charged with aggravated assault following the alleged attack on Wednesday afternoon.

According to Guelph-Wellington EMS, paramedics found the student “unconscious and experiencing some seizure activity.”

By Thursday morning, the 15-year-old was in a Hamilton hospital getting treatment for a head injury.

Danny McLaughlin, a student at College Heights, said there was a lot of yelling before a verbal dispute turned physical.

“We could actually hear through the halls the kids were screaming ‘fight, fight, fight.’ About 15 minutes later when I was walking back through the school, there were a couple police cars. We were not allowed to go through front entrance.”

The Upper Grand District School Board says it can't comment on the specific incident or whether the two teens accused of assault have been suspended or expelled.

 “The principal will also be conducting an investigation at the same time as police investigation then following that there is a wide range of disciplinary measures that are available,” said Heather Loney, Communications and Community Engagement officer with the Upper Grand District School Board

Police say the students charged with aggravated assault are both under the age of 18.

Constable Buzz Dean with the Guelph Police Service says police and school officials often struggle with enforcement around violence in high schools, but that incidents this intense are very alarming.

“When something like this happens to the extent it did, where someone ends up with some medical condition that they have to be rushed to hospital, it’s quite a concern,” said Dean.

The extent of the teen's head injury is unknown at this time.

Guelph Police and the public school board will not be releasing the names of those involved since they are minors.
