A stolen Woolworths truck has led police on a chase through western Sydney after its driver was allegedly shocked with a stun gun, assaulted and carjacked.

The driver was about to deliver his first order for the day when he was approached by a stranger on Olympic Parade in Bankstown at 5.45am today.

A Woolworths spokesperson said the employee faced ”a level of violence that is unacceptable anywhere in the community”.

The 23-year-old was checked over by paramedics before he was taken to Bankstown Hospital.

Later in the morning, police saw the truck on the Princes Highway at Rockdale and attempted to pull the vehicle over.

The driver allegedly did not stop and police started to follow the truck.

Police said the chase continued towards Wolli Creek, where the truck allegedly hit four parked cars but did not stop.

Police stopped following the truck due to safety fears but continued to monitor the vehicle from a helicopter.

The truck continued onto the M8 then travelled westbound onto the M4.

The delivery vehicle was eventually stopped by road spikes on the Great Western Highway at Glenbrook.

Police swooped in on the truck, used a Taser and arrested the man.

A 29-year-old man was taken to a nearby police station, and later to Nepean Hospital with minor injuries from the arrest.

No charges have been laid yet.

A Woolworths spokesperson said the company took the safety of its team members, customers and contractors “very seriously”.

“We’ll continue to engage with industry, police and governments across the country to drive solutions to violence across retail, including online deliveries, to help protect the safety of our team members, customers and contractors,” the spokesperson said.

“We’ll also be supporting the driver in any way we can, through our contractor, and continue assisting police with their inquiries.”

It is understood all online orders set to be delivered by the truck were cancelled and customers received a full refund.
