Booth Street fire believed to be arson

Police believe a fire at an empty residential building on Booth Street early Thursday was set deliberately, just one day after a fire nearby left 10 people homeless.

The Ottawa police arson unit is investigating an early morning fire near Little Italy.

Firefighters responded to reports of "acrid-smelling" white smoke on Lebreton Street at about 3:25 a.m.

They then declared a working fire in a vacant two-storey residential building in the 300 block of Booth Street near Willow Street.

The fire was quickly under control, firefighters said, and there were no injuries. The fire was extinguished around 4:13 a.m.

Total damage estimates are not yet available and the cause is under investigation.

Police said the fire looks to be deliberately set after early examination of the scene. This is the second fire in the area in as many days, as 10 people were left homeless after a shed on Rochester Street caught fire Wednesday.

The blaze closed Booth Street for a time but the road has since reopened.
