Members of the London police bomb unit detonated a suspicious device found in a vacant home at 820 Princess Ave. on Tuesday.

A spokesperson for the force said officers were notified in the morning about what appeared to be a small man-made pipe bomb. The disposal unit was called in, after the street was closed, and a bomb disposal robot sent in to inspect the device before police detonated it in the afternoon.

Police said later the device was found not to be an explosive, but the investigation continues.

Neighbours said the device looked like a capped pipe with a hole drilled in the end.
