“I didn’t realise it was eight — I only saw a truck there, and then a car here and another car over here, but there were lots of cops on the highway,” witness Jermaine Cruz said.
As people climbed out of their damaged cars, fists went flying.
“It is believed the driver of the truck – a 30-year-old man – was assaulted by four men before they left the scene,” NSW Police said.
It is understood the driver was allegedly stabbed in the back of the head.
He was treated by paramedics before being taken to hospital under police guard.
Four other men have been arrested, with three taken to Parramatta Police Station and one to Granville Police Station.
They are assisting police with their inquiries and no charges have been laid.
Police searched the truck and allegedly seized 30 boxes of illegal tobacco and about $42,000 in cash.
A Toyota SUV will also be forensically examined.
Police continue to investigate the incident.
