A diving lesson for a teenage girl has gone horribly wrong in West Vancouver this afternoon.
The police say the 17-teen-year old was taking part in a diving lesson, with a qualified instructor, just before 5:00.
Officials say she had to be pulled out of the water at Whytecliff Park, and dragged to the beach by other divers.
The teen was unconscious and was quickly airlifted to hospital.
She is in critical condition.
The police say the investigation is ongoing.
