Police urge longboarders to consider safety after 4 people injured

WEST VANCOUVER, B.C. - Police in West Vancouver are pleading with longboarders to consider their personal safety after four people injured themselves on the streets in the last two weeks.

Two men in their 20s were hospitalized Wednesday after they collided with a parked truck while longboaring.

Const. Jeff Palmer said a 23-year-old man from Surrey was released from hospital Wednesday night and that a 20-year-old male from North Vancouver was expected to be going home later Thursday.

A 17-year-old boy from West Vancouver who suffered serious head injuries while longboarding on May 24 remains in intensive care.

A 19-year-old male had facial cuts after slamming into a vehicle in West Vancouver on Monday, but Palmer says he could have been seriously injured after ending up underneath the car.

Longboarding is prohibited on all public streets in the District of West Vancouver, and police are urging riders to seek out organized events that aren't open to vehicles.
