Coast home torched room by room
THIEVES are believed to have gone from room to room starting fires in a $800,000 family home that was destroyed in the blaze at Eumundi.
And last night police were hunting for a black BMW convertible that they believe was stolen from the house before it was burned.
The fire started about 8am yesterday.
Police believe thieves could have started the fires throughout the house to try to hide their raid.
No one was inside the home when fire crews arrived. The owners, who were not named, were understood to be on holiday in Bangladesh.
The Daily understands several fires had been started in each room. Alcohol was believed to have been used as an accelerant.
Police are now seeking information on the BMW. It was seen being driven from the area a short time afterwards.
About 14 firefighters from Nambour, Cooroy and Eumundi worked to extinguish the fire, which burned for an hour. Most of the internal rooms and downstairs garage were charred and cladding on the exterior of the house was blackened.
Nambour Fire Service station officer Fred Heiniger said the fire was well alight when crews arrived.
"There was extensive damage from the smoke and heat, although the external structure and roof remained intact."
Firefighters used breathing apparatus to search the property for occupants before water was used to extinguish the fire.
Investigations will continue today.
Police asked anyone with information or who may have seen the Black BMW convertible, registration HSN00, to contact Crime Stoppers on 1800 333 000.
