Car crashes into Sydney house

At least one occupant of a car that crashed into a Sydney home could have been involved in an argument with someone in another vehicle before the incident, police say.

Emergency services were called to Rosemeadow in Sydney's southwest on Saturday afternoon following reports the car had crashed into a house.

No one was inside the home but police say it sustained significant structural damage.

The 39-year-old female driver and her 18-year-old male passenger were uninjured and police inquiries into the incident are ongoing.
