A man has died after being shot by police outside a house in Perth's northern suburbs.
The shooting happened in front of a home on Macdonald Avenue in Padbury around 10pm last night after local police were called to support St John Ambulance.
Speaking at the scene, WA Police Superintendent Tony Flack said officers had approached the residence's front door when a 35-year-old man rushed towards them, armed with a knife, naked and covered in his own blood.
"Unfortunately they've had to discharge a firearm and he is subsequently dead," he told reporters at the scene.
"I can only say that a large naked male running at you at speed with a knife, you have to act really quickly and really professionally, and I'm very proud of the way the officers handled themselves.
"They certainly prevented further injury."
Superintendent Flack said the people living at the house had called an ambulance after the man had inflicted wounds to his own neck.
"He was bleeding profusely, and they called him in as a medical emergency," he said.
Officers remain at the scene, with a police investigation underway.
More to come.
