A BLAZE at a derelict building in Hartlepool has sparked a police probe.
Firefighters from Stranton and police were called to The Cottage in Manor Lane, at 6.15am today.
A fire had been started in the derelict property - which was last hit by arsonists less than a fortnight ago.
It is thought the fire had been burning for at least half an hour before crews were alerted.
The blaze has left the property, according to firefighters “substantially damaged.”
It has now been boarded up. Police and firefighters are now monitoring the property.
