A woman has died in a western Sydney home and a mother has been arrested after a car crashed into the property in the early hours of Saturday morning.
Emergency services were called to the Monfarville St home at St Marys after 5.20am following reports a black Jeep station wagon had driven through the house.
One of the four occupants of the home, a 62-year-old woman, was treated by police and paramedics but died at the scene.
The other three occupants were not injured.
A large hole where the car had ploughed through was left at the front of the home, while debris from the vehicle had launched into a nearby tree.
Photographs from the scene show the car badly crumpled in the backyard, suggesting the vehicle ploughed through the entire house.
Blacktown Fire Station Officer Samuel Parkhouse said the house had sustained “significant structural damage”.
“It appears the car as its come into the property has become airborne and has gone straight through from the front,” he said.
While attending car crashes is a regular occurrence for firefighters, Officer Parkhouse admitted he had never seen a car that had “drifted all the way through” a house before.
Fire and Rescue had to use specialised equipment to maintain the structural integrity of the house.
“We use that equipment to shore up the structure to maintain its structural integrity to make it safe for ongoing investigations,” Officer Parkhouse said.
Following the crash, police stopped a 29-year-old woman who officers allege fled the scene of the crash with her baby.
She was subsequently arrested and taken to Nepean Hospital for mandatory testing.
Both the woman and her baby were uninjured.
The family who live in the Monfarville St home are well known by locals in the St Marys community.
Many onlookers looked visibly upset and stunned as they surrounded the crash site on Saturday morning.
One resident said the 62-year-old woman regularly “sat on her front veranda” and would often wave at people.
A shocked witness told 9News there were “no brakes or “nothing” when the crash occurred.
“It was just, yeah, just a boom,” he said.
The black station wagon was taken away from the property after 12pm by authorities.
The front of the car was unrecognisable, with a destroyed bumper, bent bonnet, and compressed and shattered windscreen.
The doorframes of the left side of the vehicle were also hanging loose.
An investigation into the circumstances surrounding the crash has started.
Officers from Nepean Police Area Command have established a crime scene, which will be examined by specialist police from the Crash Investigation Unit.
Anyone with information, dashcam or CCTV has been to contact Nepean police or Crime Stoppers on 1800 333 000.
