Three men have been charged following a pursuit in Sydney’s west involving an alleged “kill car”.

Raptor Squad detectives attempted to stop an allegedly stolen Audi on the Great Western Highway in Wentworthville, about 2pm on Saturday before a police chase through a number of suburbs.

During the chase, police said the offenders were seen throwing fuel jerry cans and bleach containers from the car.

The vehicle was rammed by police along Hill Road in Lidcombe and the men attempted to flee the scene on foot.

Police – with assistance from PolAir and the Dog Squad – arrested all three men a short time later.

Footage obtained by the ABC shows one of the men being detained by several police officers underneath the motorway where the stolen Audi had been stopped.

During a search of the vehicle, police said a semi-automatic rifle, a pistol, and cloned number plates were found and seized.

Police said the Audi, which they suspected to be a “kill car”, was reported stolen from an address at Edmonson Park in March.

“Kill cars” are vehicles that have been stolen, sometimes months in advance, have cloned plates and contain a kit to commit and get away with murder.

Overnight, the trio were charged with possession of an unregistered and prohibited firearm, possess an unregistered and unauthorised pistol in public place, possess ammunition without holding a licence or permit, and participate in a criminal group and contribute to criminal activity.

The 28-year-old driver was charged with two additional offences for drive conveyance taken without consent of owner and police pursuit — not stop — drive recklessly.

He had two outstanding warrants executed for assault and domestic violence offences.

The two 24-year-old men were charged with being carried in conveyance taken without consent of owner.

The three men were refused bail and are due to appear before Bail Division Local Court today.
