A man has been shot and killed in a violent attack on a suburban street in Sydney's west.
The man was found with gunshot wounds after reports of a shooting on William Street at Fairfield about 2.40am on January 10.
The 34-year-old died at the scene despite efforts from emergency services to revive him, NSW Police said.
Detective Acting Superintendent Glen Fitzgerald said the man was well known to police, who would investigate if the incident had any links to gangs or organised crime.
"We believe the attack to be targeted. He is well known to police," the Fairfield City police commander said.
"This is a violent attack on a suburban street, and it's totally unacceptable behaviour."
A crime scene was established and sections of William Street and Harris Street were closed.
