Crews from Kidsgrove and Biddulph were called to a fire involving a caravan and the adjacent property on Sands Road in Harriseahead at 1.40am this morning.
"There are suspicious circumstances surrounding the fire and so a joint investigation alongside the police is required to determine the cause."
Station Manager, David Agu
Firefighters wearing breathing apparatus used one main jet to extinguish the fire, which began in the caravan. The fire has destroyed the caravan as well as damaging the adjacent property and both neighbouring properties.
The properties involved have all suffered from severe heat damage and both neighbours had to be evacuated whilst firefighters brought the fire under control. The owner of the caravan and occupant of the house was not inside the property when the fire began.
Crews left the scene at 5.10am and then one crew from Kidsgrove returned at 7.45am this morning to check for hotspots. Thermal imaging cameras were used to identify any remaining hotspots and firefighters used one hose reel jet to damp down before leaving the scene again at 8.15am.
Station Manager, David Agu said: "There has been significant damage to the properties involved and the caravan has been completely destroyed. There are suspicious circumstances surrounding the fire and so a joint investigation alongside the police is required to determine the cause."
Fire Investigation Officers and Scenes of Crime Officers returned to the scene at 9.00am this morning to carry out a joint investigation.
