Vancouver Transit Police taking extra precautions prompted by London blast.

Vancouver Transit police have been performing extra security sweeps across the Metro Vancouver SkyTrain system in the wake of Friday’s subway bombing in London.

Officers wearing high-visibility vests and assisted by explosives-detecting dogs did additional checks throughout the morning as a precaution.

Though no local threat have been reported by intelligence, but police are still encouraging transit users to contact them if they see anything unusual.

Friday's attack, which injured 29 people, is the fourth terror incident committed in London so far this year.
