VANCOUVER -- Police are investigating after the body of a young man was found at the base of a seaside cliff in Vancouver's Stanley Park.

Officers responded to calls about a body found on the seawall walkway (near Siwash Rock) shortly after 4 a.m. on Sunday.

A 23-year-old man was declared dead at the scene.

Police say they believe the man was attending a rave in a secluded area of the park (along Merilees Trail above Siwash Rock) when he tumbled off a cliff to his death.

They say the incident appears to be accidental and that officers have not confirmed whether drugs or alcohol were involved.

Anyone with information about the event is asked to contact the Vancouver Police Department.
