Five teenage girls have been arrested after leading police on a high-speed car chase in Sydney's west that ended in a crash.
NSW Police say dog squad officers spotted the stolen car speeding just before midnight on Monday on the Great Western Highway at Bungarribee.
Police tried to pull the car over but it failed to stop, leading to the pursuit.
"A short time later, the vehicle failed to navigate an intersection and hit a truck," police said in a statement.
The five girls fled on foot into nearby bushland but were arrested and taken to Mt Druitt Police Station.
The alleged driver, a 17-year-old girl, was treated by paramedics for dog bites sustained in the arrest.
