Two children were pulled from a burning car by their mother, who had left them alone in the vehicle while she went to the bank.
A 6-year-old boy and 22-month-old girl were in the car on Baxter St, Warkworth, yesterday when the boy found a cigarette lighter in the car.
Warkworth chief fire officer Ian Davies said the lighter was used to start the fire.
"He was playing with a cigarette lighter and set fire to the rear of the driver's seat, right where his sister, a 22-month-old, was sitting," he said.
The children's mother was across the road from the parked car, inside a bank. She pulled the 6-year-old out of the car but struggled to remove the baby in the child restraint.
