A wild high-speed police chase across Melbourne that involved collisions with multiple cars has ended with the driver being hit by an unmarked police car.
9News understands a white van initially collided with cars in the Domain Tunnel before the male driver took police on a pursuit through the south-east.
The 9News helicopter captured the wild chase as the heavily damaged van travelled, on its rims with sparks flying, back towards the city on the M1.

Helicopter footage showed the van weaving in and out of traffic on the West Gate Bridge, clipping multiple cars and narrowly missing dozens of other vehicles.
After appearing to speed up the West Gate Freeway and onto the Princes Freeway for about 15 minutes, the van exited the freeway at Palmers Road in Point Cook.
After performing a sharp right turn onto Dunnings Road, the car sped through two street signs, which became snagged under the front wheels of the van.
Los Angeles style freeway chase with police and all.
Should make the national news.
Why did the police decide to run him over?
