Video footage has captured a shooting spree outside a Melbourne boxing event last Friday night that left one man dead and two others fighting for their lives.

Taken from a car travelling down Stubbs Street at 10.02pm, the dashcam video shows several men fleeing the scene after up to a dozen shots are fired outside the Melbourne Pavilion in Kensington.

Several vehichles almost collide as they attempt to avoid the gun battle, while pedestrians run for cover.

A 30-year-old man from Craigieburn died at the scene after being shot in the head, while two other men, a 34-year-old from Lalor and a 32-year-old from Craigieburn, were critically injured in the brutal attack.
