Woman Burned, House Firebombed In Alleged Domestic Violence Attack

A woman has been left with burns to 30 percent of her body after a man allegedly set her alight before throwing a firebomb into her Perth home.

A 51-year-old man, who is known to the woman, has been charged over the arson attack.

WA Police allege the Wandina man went to the home on Hooley Road in Midvale at about 8:50pm on Sunday, where he threw burning material over the 52-year-old woman.

On his way out of the house, police say he then threw an "incendiary device" into the home.

The woman suffered serious burns, mainly to her head, neck and throat, and is currently in a critical but stable condition at Fiona Stanley Hospital.

The Midvale home suffered damage worth an estimated $150,000.

A neighbour rushed over to the home after he felt his own house shake from an "explosion" and heard the woman's screams.

"I've come to the door and seen a man with another Molotov cocktail in his hand," Robert Caverley said.

"He threw that, and then he walked off. I ran out to see if she was okay and she was pretty badly burnt."

Caverley said he ran into the burning house to retrieve a man who was still inside, before putting a wet towel over the injured woman.

"Then I ran up to the flaming windows and turned the gas main off, and I turned the gas main off the two houses next door," he said.

Robert Caverley came to the injured woman's aid after hearing her screams.

The fire caused an estimated $150,000 worth of damage.

After his arrest, the suspect was taken to hospital for treatment of serious burns to his hands.

He was charged with causing grievous bodily harm with intent and criminal damage by fire, and will face a bedside hearing on Monday.
