Two teenagers are in a serious condition in hospital after apparently swallowing a significant amount of heroin.
A border guard at YVR became suspicious early Sunday morning and detained the 17- and 18-year-olds as they tried to board an international flight.
According to various media reports, the pair were arrested and are said to be in serious condition in hospital.
Few other details have been released and police have not said if the drugs have been recovered.
