A woman who suffered serious injuries in a hit-and-run in Sydney's west is believed to have been deliberately run down in a car park.
The 40-year-old woman was taken to Westmead Hospital with a fractured pelvis after she was struck by a vehicle that accelerated towards her in Woodcroft on Thursday night.
Detective Senior Sergeant Wayne Kelly, from Blacktown police, said the woman had arranged to meet a man in a car park off Antique Crescent in Woodcroft and arrived about 7.30pm on Thursday in the company of another man.
However as the woman stood in the car park, a man driving a charcoal-coloured Mazda CX7 accelerated towards her and ran her over.
"We don't think it was an accident," Detective Sergeant Kelly said.
"Whether it was deliberate or criminally reckless, we're yet to determine."
The man then drove away as the woman lay injured on the ground. His vehicle allegedly hit another car as it left the car park.
Paramedics treated the woman at the scene before taking her to Westmead Hospital, where she remained in a stable condition on Friday morning.
Detective Sergeant Kelly said the driver of the vehicle was believed to have been known to the woman.
He said detectives hoped to interview the woman by midday on Friday. It was unclear why she had originally arranged to meet a man in the car park, Detective Sergeant Kelly said.
The 35-year-old man who arrived at the car park with the woman was arrested at the scene for an alleged breach of bail, which was related to another matter, Detective Sergeant Kelly said. He was not the driver of the vehicle that struck the woman.
There are not believed to be any CCTV cameras near the car park.
Forensic officers examined the car park on Thursday night, and detectives searched the area and spoke to a number of people.
They have appealed for anyone with information about the hit-and-run to contact Blacktown police or Crime Stoppers on 1800 333 000 or visit the Crime Stoppers online reporting page.
