A teenage boy is in intensive care with spinal injuries after allegedly crashing a stolen car into a stone wall in Wollongong, police say.
Authorities said on Thursday morning they were still trying to contact the parents of the 15-year-old boy, who is in a critical but stable condition at St George Hospital.
Police allege the boy took the keys to a high performance Holden Commodore from a Farmborough Heights house on Wednesday afternoon and then drove the car along Farmborough Road at high speeds before mounting a kerb and crashing into the wall.
"A number of witnesses observed the vehicle being driven in an erratic manner at speed," Inspector Gary Castle, from Lake Illawarra police, said. The car ended up on the front lawn of a house.
Emergency services initially received reports that someone was trapped in a car but when they arrived at the scene, the boy had managed to escape the wreckage, police said.
Inspector Castle said the boy lost consciousness shortly after he got out of the car.
He was treated at the scene and airlifted to St George Hospital with lung and spinal injuries.
Police have called for anyone with information to come forward.
