Police say a device found on the elevated tracks of the SkyTrain line in Surrey, B.C., Friday was an explosive.
Transit Police spokeswoman Anne Drennan says the object was spotted by a passenger on the tracks between the Scott Road and Gateway stations.
She says the device looked like a small propane tank with straps and wires attached.
A bomb squad was called and recovered the device, and police are looking at surveillance video for any clues about who left the object on the tracks.
The incident disrupted service on the SkyTrain system between the Scott Road and Gateway stations for about three hours.
