The officers were immediately confronted by a man brandishing a knife and threatening them. The suspect was shot in the chest by police, Clayton said. He has since been transported to the hospital under police guard and is in a critical condition.
No other suspects are being sought. Clayton said there is no known link to terrorism, but stressed the investigation is still in its early stages.
The incident took place in Melbourne’s Central Business District on Friday afternoon when people would have been leaving work. Photo from the scene showed crowds of people behind police barriers.
Witnesses said they heard a big bang and images appeared to show a car on fire.
“There was a massive flame and bang, just smoke and lots of people,” witness Shelley Reid told Nine News.
Streets were closed and trams halted while police attend the scene.
