Regional Police arrested two people after a storage shed was set on fire in Glace Bay early yesterday morning.
Police say they got the call to 87 Highland Street at around 7:00.
They add the nearby house is vacant and the matter remains under investigation.
Fire officials say they believe the blaze is an isolated incident and not connected to a rash of arsons in the CBRM over the last month.
The police arson squad has been investigating nine fires that were set in Sydney, Sydney Mines and New Victoria.
