Vancouver Police are investigating after a teenager was seriously injured in a stabbing following a high school basketball game at Eric Hamber Secondary Monday night.

 The assault occurred shortly after 9 p.m., as a game between the Eric Hamber and Killarney Secondary basketball teams was concluding.

 Police believe fights broke out between spectators, resulting in an 18-year-old boy being stabbed in the arm. The stabbing victim was taken to hospital and received medical treatment.

 No arrests have been made.

 Police are asking anyone who took cell phone video during the fight, or while the game was taking place, to submit video online. A web portal has been created for submissions.

 Witnesses, or anyone with information who has not yet come forward, can also contact VPD’s Youth Investigative Unit at 604-717-0614.

 Additional school liaison officers are being deployed to both schools. They will provide additional support and conduct safety planning with staff and administrators.
