ARSON Squad detectives are investigating the lighting of two cars outside a home in Ellenbrook early this morning.
The resident of the Santorini Turn house woke to see the cars on fire out the front of her place and police and firefighters were called about 2.35am.
A bottle with liquid had also been thrown at a front window and two other vehicles had their windows smashed and had been doused with an accelerant.
Midland detectives are also investigating.
Anyone with information can call Crime Stoppers on 1800 333 000.
