Transit Police confirm it was an explosive device found on the Skytrain tracks Friday afternoon in Surrey.
The RCMP Explosives Device Unit has determined it was an explosive device attached to three empty cannisters.
It was spotted on the guideway track by a passenger on the Skytrain between Scott Road and Gateway Stations around two Friday afternoon.
Transit Police spokesperson Anne Drennan says she doesn't know how much damage could have been done had it gone off.
The rest of the Skytrain line is being checked and Drennan says all measures taken will be reviewed.
