A family has lost their home in a house fire that Parkes Police are now treating as suspicious.
Along with crews from Parkes Fire and Rescue NSW and the Rural Fire Service, police were called to the house fire in Thomas Street just after 7pm on Thursday.
They found the house fully ablaze when they arrived.
A second residential fire occurred at the same time on the other side of the Newell Highway at Parkes, in Wentworth Street, but police have deemed it not related.
Chief Inspector Dave Cooper said firefighters worked on the Thomas Street premises for a number of hours to get the fire under control.
The house was destroyed.
"Fortunately everybody was accounted for," he said.
"Police investigations will continue on the basis that there may be some elements of the incident that are suspicious."
Chief Inspector Cooper said some of their observations at the scene is what has led them to believe the incident may be suspicious.
Police have no suspects as yet.
"We maintained the crime scene guard overnight and the scene is currently being examined by crime scene officers," Chief Inspector Cooper said.
"My understanding is that the owners of the premises were not present at the time.
"At the same time another house fire was reported in Parkes - that fire was completely and totally unrelated."
Police believe the fire in Wentworth Street - where firefighters found smoke and flames in the ceiling space - was a cooking incident.
"It was attended by police and fire brigades as well and the elderly resident was conveyed Parkes Hospital," Chief Inspector Cooper said.
