A blaze ripped through a house in Knottingley.
Three fire engines were called to Hazel Road last night (Thursday).
And the fire left the house gutted.
A spokeswoman for West Yorkshire Fire and Rescue Service confirmed they are investigating the incident.
Crews from Normanton, Featherstone and Wakefield were called to help extinguish the flames , at around 11.32pm.
No-one is thought to have been injured .
Mark Hutley, 62, lives nearby.
He said the home had been empty for few weeks.
Mr Hutley said: “People have been messing around at the back of the house for a while now because it wasn’t completely secure.
“I’m concerned now because the front door and window is gone now after the fire and it is wide open.
“It’s a real target now for arsonists and vandals.”
