SA Police are searching for a stolen car with a four-month-old boy in the back seat in Adelaide.
They say a 2009 white Honda Jazz hatchback, with the registration S619AXE, was stolen from outside the Fourth Ave Deli on Fourth Avenue, Klemzig, about 7:45am.
The owner, a woman, had just put her child in the back seat when a man pulled up in a stolen Mazda ute and switched cars.
"It appears to be random at this stage," Senior Constable Gen Cullinan told ABC Radio Adelaide.
"It would appear they've dumped one car and then literally tried to take another car so there's no indication these people are known to each other."
The stolen Honda was last seen heading towards Windsor Grove, which is at the eastern end of Fourth Avenue.
The man has been described as Caucasian, aged in his mid-20s, with dark hair.
Police have asked anyone who sees the Honda Jazz to call 131 444 or triple-0.
Senior Constable Cullinan urged people not to try to pull over the car themselves.
The deli owner, who only wanted to be known as Allan, said the female driver of the stolen hatchback came in to buy some items but then ran out when she saw her car take off.
"She was hysterical and asked for a phone to ring the police and that sort of thing, which she did. And they weren't too long coming," he said.
"I'm worried about the child… I just hope the baby's OK – that he realises there's a baby in the back and leaves the car."
