Shots were fired at a house in western Sydney early on Saturday morning.
It was the city's third shooting this week, but three women inside the house in South Granville were not harmed.
Inspector Matthew Hyde of the Granville police said officers were investigating whether other people lived at the western Sydney home.
It's not yet clear how many gunmen were involved, whether they were in a car or how many shots were fired, he told AAP on Saturday.
On Friday a man was killed in a shooting while standing in the front of a hoise at Abbotsbury, in west Sydney.
AAP reports another man was shot dead when a drive by gunman opened fire on him and two bikie associates as part of a dispute with another outlaw motorcycle gang at Eastlakes on Monday night.
Investigations into all three shootings continue.
