“During the highly dynamic incident it is believed the male produced an edged weapon and was shot by police,” a police spokeswoman said.
Paramedics treated the man for upper body injuries at the scene before he was taken by air ambulance to hospital. He has since died.
“The investigation is in its infancy, detectives from the homicide squad will investigate to determine the exact circumstances on behalf of the coroner, which will be [overseen] by Professional Standards Command, as per standard protocol when a police firearm is discharged,” a police spokeswoman said.
A caller to Melbourne radio station 3AW, identified only as Brock, said the man was being chased by police before he collided with an oncoming car.
“He proceeds to get out of his car and run towards my car holding something in his hand,” he said.
“It must have been a weapon of some sort because the police were yelling at him to drop it. He didn’t drop it and was shot twice.”
Brock said police “gave him every opportunity to stop”.
