A man has been left with broken limbs after being involved in a horror head-on collision with a police car in Sydney's west.
Police attempted to pull over a white VW Golf travelling in Dean Park in the city's west for a random breath test and gave chase when the driver failed to stop about 10.15pm yesterday.
The pursuit, which involved up to 10 police cars, stopped when officers lost sight of the car, and the VW Golf and its occupants still haven't been located.

A marked police car from Nepean Area Command and a Holden sedan had a head-on collision just minutes later on Debrincat Avenue in North St Mary's.
CCTV footage of the crash shows the Holden pulling out onto the road before being hit by the police car.
The crash was so loud that neighbours quickly came rushing out of their homes to offer assistance.
"[I] heard the bang and came out, unfortunately there was somebody in a bad way," neighbour Rowan Thorpe said.
The 47-year-old driver of the Holden sedan suffered injuries and was taken to Westmead Hospital in a serious but stable condition.
Police later confirmed he had suffered a broken arm and leg.
The 25-year-old male police constable driving the police car and a 25-year-old female senior constable passenger, who was pregnant, were treated by paramedics at the scene and taken to Nepean Hospital.
They have since been released and are believed to be recovering well.
Assistant Commissioner Gavin Wood said the officers involved in the crash were acting on information given to them by the public.
Wood said police were "deeply sorry" for the victim but said it was too early to put the blame for the crash on either party.
He reiterated the pursuit had been called off at the time of the accident.
"The police vehicle itself had received relatively new and contemporary information from a member of the public, and they acted accordingly," Wood said.
"Their reaction wasn't [because of] a pursuit per se, they were reacting to the information given to them by members of the public."
A critical incident investigation into the circumstances of the crash is underway, where the actions of the police will be examined.
