Terrorism on the Sky Train?

RCMP are investigating what appear to be four propane tanks lashed together and left on the Sky train commuter rail tracks in Surrey, B.C.

"It certainly does appear suspicious in nature where we have several propane tanks that have been purposely strapped together and placed in a bit of a precarious position," Sgt. Drew Grainger said.

"We've cordoned the area off and we have activated the explosives disposal unit to give it a much more comprehensive assessment."
