In the fight that ensued, one of the non-students, a 19-year-old man, was stabbed.
“They went looking specifically, it appears, for a student or a group of students,” said Hadley.
“That’s probably why the police suggested that it’s not random.”
Police say the man who suffered the stab wound was transported to hospital with undetermined injuries. No one else was injured in the incident, police said in a news release.
Hadley said the stabbing occurred in the front entrance of the bus, near the door. There were several students on board waiting to go home.
Another school bus was dispatched to drive the rest of the students home, but many had to stay behind to answer questions from the RCMP.
One concerned mother on Facebook said her 15-year-old daughter had seen what happened and was “was very, very shaken.” Contacted later, she said her daughter was “pretty upset by what she saw.” Police are currently looking for the suspect.
