Three people have died in a horrific head-on city car crash, including a man who sped away after police arrived at a home to conduct a welfare check.
A 42-year-old man drove off in a white Audi after officers were called to a mental health incident at a property in Gymea Bay, southern Sydney, at 12.25am on Saturday.
Shortly afterwards, police received reports an Audi had rolled over a concrete barrier and landed on a blue Toyota sedan at Sans Souci, about 13km away.
The man died at the scene, as did the driver and passenger of the Toyota, who are yet to be formally identified.
Police were unable to speak to the man at the home before he drove away, Detective Acting Superintendent Graham Hibbs told reporters.
