Firefighters in the Cape Breton Breton Regional Municipality were kept busy with a handful of suspicious fires Thursday night.     

Two homes in Florence went up in flames around 8 p.m. Both fires were on Highball Street.    

One home was a seasonal residence and neither building was occupied at the time of the fires.   

Both buildings suffered significant damage, police said.

Police also found some sort of an accelerant inside a vacant structure in the same area, but had not been ignited when police and firefighters arrived.  

Florence is 3.6 kilometres north of Sydney Mines.

In New Waterford, half of a duplex caught fire on Larch Street around 7:15 p.m. It caused significant damage to the rear of the building.  

The person who lived in the unit that caught fire was home at the time of the blaze and wasn't injured.    

No one was home in the other half of the duplex.

Both the fire marshal and police are investigating the suspicious fires.
