A MAN who crashed into Christmas shoppers near Rundle Mall, injuring four female pedestrians, has been arrested in his hospital bed at the Royal Adelaide Hospital.
The 40-year-old driver from Hampstead Gardems who was displaying P-plates, is believed to have crashed as he tried to turn right into Rundle St from Pulteney St, just after 4pm on Saturday.
The man, who is known to police and is believed to have recently finished a stint in jail, is expected to be charged with causing serious harm by dangerous driving as well as other serious charges relating to the crash.
Police said they were not treating the crash as a deliberate act but police that reckless driving played a factor in the crash.
The crash left the driver in a serious condition after he lost control of the car and crashed into Christmas shoppers near Rundle Mall in the CBD.
Witnesses have described their horror as the car lost control and careered in pedestrians before hitting the pole.
His car hit pedestrians, who were waiting to cross the road near Target, and came to a halt after crashing into a traffic light.
Superintendent Craig Wall of the Eastern Adelaide Local Service Area said that while they could not initially rule out whether the crash was deliberate they had made progress in investigation.
"Police are investigating the circumstances surrounding the crash but they are not treating the incident as a deliberate act," Superint Wall told The Sunday Mail.
Rowen Osborne, 15, who was waiting to cross at the lights, saw the car lose control and said a woman was left injured and screaming in the middle of the street.
"The car just came off the road and went into the pole and the pole crumpled with it and smoke started coming out of the body (of the car)," Ms Osborne said. "A woman was screaming 'help me, please come and help me'.
"Another woman was flung into the gutter and lay there motionless.
"It was terrifying, it was random and out of nowhere. It was horrific.
"We rushed over to try and help but there wasn't much we could do.
"We could see the driver just sitting there not really responsive at all."
Four female pedestrians were injured in the crash and taken to hospital.
A 67-year-old woman from Dulwich with multiple injuries and a 32-year-old woman from West Croydon who suffered leg injuries were taken to the Royal Adelaide Hospital.
A 67-year-old woman from Heathpool who suffered leg injuries and a 26-year-old woman from North Adelaide with minor injuries were taken to the Flinder Medical Centre.
Dozens of people hurried to help the injured pedestrians and driver in the minutes after the crash as emergency services rushed to the scene.
A bystander said he heard a "god-awful bang" and came out of a shop to find a female lying in the middle of the intersection.
Other injured pedestrians were on the footpath and the bystander said the occupants of the car were initially trapped in the crash.
A MedSTAR helicopter circled overhead as at least five ambulance crews attended to the injured.
Traffic restrictions have been removed at the intersection between North Tce, Grenfell St and Bent St.
Major Crash investigators have attended the scene.
