Car slams into Sydney home

A car has slammed into a house in Sydney's southwest and landed on a sleeping woman's bed.

The 50-year-old woman driving the car, reportedly a P-plater, first hit a parked car before reversing into the side of a home in Green Valley early on Wednesday.

A 46-year-old woman inside the home was sleeping when the car crashed through her bedroom wall.

Her son, Grant Alexander, said she suffered bruising and swelling.

"The car was parked on my mum's bed," Mr Alexander told The Liverpool Leader newspaper.

"I checked she was all right and ran outside to check the (other) woman was all right and shut the car off because it was pumping fumes into the house."

The driver also suffered minor injuries, and has been taken to hospital for blood testing.
