Police continue with their investigations after a fail to stop crash at Blacktown this afternoon, NSW Police say.
Shortly before 3pm today a Holden Commodore sedan was travelling north along Main Street.
Police have been told by witnesses that the vehicle was being driven erratically and at the intersection with Newton Road the Holden was driven between vehicles that were stationary at a red traffic control signal.
The Holden struck one vehicle but continued until near the intersection with Warrick Lane the Holden crossed to the wrong side of the road to pass stationary vehicle and struck a 61-year-old man on a pedestrian crossing.
Although the man was carried on the vehicle for a short time the Holden continued and made a right hand turn into Warwick Lane where it eventually stopped.
Police believe that a man, woman, and new born baby fled from the Holden which then returned to the pedestrian crash scene.
The injured man was treated at the scene and conveyed to Westmead Hospital in a stable condition where he will undergo surgery to a head injury.
Officers from Blacktown Police Area Command and the Crash Investigation Unit attended and the 47-year-old female driver of the Holden was arrested.
At Blacktown Police Station, the woman was charged with dangerous driving occasioning grievous bodily harm, negligent driving occasioning grievous bodily harm and drive furiously.
She was refused bail to appear at Parramatta Bail Court tomorrow.
Police have spoken to the other woman in the car who remains in hospital after a mental health assessment while the child is in the care of another government agency.
Investigators continue with their inquiries into the incident and to locate the male passenger from the Holden.
