Police have arrested a male youth in connection to an assault near St. John's High School that sent four people to hospital, one man with stab wound to his arm.

A 13-year-old male has been arrested and charged with assault with a weapon, possession of a weapon and possession of a concealed weapon.

Witnesses say a fight starting at a park across the street from the school and eventually ended up in front of the school's door steps.

They say both parents and students were involved.

There were attempts to break up the fight, but it got worse. Verbal threats turned into someone pulling out pepper spray.

“The guy comes up and starts punching the kid. And the mom comes up and starts attacking his girlfriend. And then some guy pulled out a can of bear mace and started spraying him and he got sliced right here in the arm," said Jewles Morrissette, who witnessed the incident.

A woman who identifies herself as the mother in this situation contacted CTV News and disputes this account of what happened.

"I was freaking out. I was scared. I was going to have an anxiety attack. I was really scared," said Jessica Croft.
