Four teenagers are in hospital with serious injuries after the car they were travelling in hit a power pole and smashed through the front fence of a home in Sydney's west.
Police say the teenage boy who was driving the white Peugeot sedan was unlicensed and are investigating whether he was speeding when the vehicle crashed in Blacktown early on Wednesday.
Inspector Adam Powderly, from Blacktown Police, said three of the people in the car were aged 15 and one was aged 16, but the age of the male driver was unclear.
"No-one in the car would have been eligible for P-plates," he said.
The vehicle was travelling east along Bungarribee Road about 1.40am when it mounted the gutter, overturned and struck a power pole before crashing through a brick fence at the front of a home.
Police, Fire and Rescue NSW officers and paramedics were called to the scene and freed a teenage boy who was trapped inside the driver's seat.
The teenagers - two boys, and two girls - all suffered serious injuries and were taken to Westmead Hospital.
Inspector Powderly said the car was not reported stolen and officers were investigating whether the car belonged to one of the teenagers’ family members. He could not confirm a report that the car belonged to the driver’s grandmother.
A family, including an eight-day old baby, were believed to be inside the home when the vehicle crashed through their front fence, and a number of bricks smashed into the side of the house.
Inspector Powderly said one of the teenagers had to be cut free from the wreckage.
"There was fairly significant damage to the vehicle. Three of the teenagers were out of the vehicle at the time police arrived, but the last young person had to be cut out," he said.
Police were investigating whether speed or alcohol was a factor in the crash.
East-bound lanes of Bungarribee Road were closed while police examine the crash scene.
Police are appealing for anyone with information about the crash to contact Blacktown Police via Crime Stoppers on 1800 333 000.
