Woman struck by car in Chatswood
Police continue to make inquiries after a woman was hit by a car on Sydney's North Shore on Friday morning.
It first struck a pram, before hitting the woman who was walking nearby along the footpath.
The vehicle then crashed into a pole, hit a motorbike and flipped onto its side, coming to rest on the footpath outside a Chinese restaurant.
Remarkably, the child in the pram was not injured but has been taken to a medical centre for precautionary checks.
The injured woman has no connection to the child, police said.
NSW Ambulance paramedics and CareFlight's medical team treated the woman, aged in her early 30s, for head injuries before taking her to Royal North Shore Hospital in a critical condition.
A witness, Oubie Elrish, was on Victoria Avenue getting coffee with his brother when the crash occurred in front of him.
"All we know is that he [the driver] mounted that curb, lady was walking that way, [the car] collected her, collected the second lady," Mr Elrish said.
"The second lady was alright, but the first lady was all bloodied and bruised. It wasn't a good sight.
"We just had her in our arms, and she wasn't too well."
He said it was "very lucky" only one person was injured, given how busy the shopping strip usually is.
A NSW Police spokeswoman said police had been told that the child in the pram was not injured and was taken by family to a medical centre to be checked as a precaution.
"Police are yet to confirm the child's age or sex," the spokeswoman said.
Police are understood to be investigating whether the 67-year-old male driver of the vehicle suffered a medical episode before crashing.
The driver was treated at the scene for minor injuries. He was taken to hospital for mandatory blood and urine testing, police said.
