Police say a 17-year-old male student suffered a minor knife wound after an altercation in an Oshawa high school parking lot.
Investigators say officers were called to Monsignor Paul Dwyer Catholic High School at about 11 a-m after a student came into the school with an apparent knife wound on his side.
The victim, who was alert and talking, was taken to a local hospital by ambulance.
Police say the suspect is a passenger in a blue van that had pulled alongside of the victim as he walked towards the school.
