Suspicious fire guts abandoned home

A suspicious fire has gutted an abandoned home in Melbourne.

Authorities were called to a Melton West property overnight after the home was completely engulfed in flames.

Fire crews urgently tried to contain the blaze so it didn't spread to nearby grassland.

The cause of the fire is still unknown, although authorities said it's being treated as suspicious.

At least 12 fire trucks were called to the property.

It took crews nearly an hour to get the fire under control. 

Fire investigators will arrive at the scene later this morning. 

Anyone with information is urged to contact Crime Stoppers on 1800 333 000.
