A man is fighting for life after being shot in what police described as an planned ambush, marking the second shooting in suburban Sydney in as many days.
"It appears he was coming home from work and ... there was an ambush style-attack," Superintendent Steve Egginton said on Thursday.
Police were called on Wednesday night to a home in Blackett in western Sydney where they found a 29-year man with gunshot wounds to his body and head.
"A number of rounds were fired through the windscreen of a car that impacted with the victim while he was seated in the car," Supt Egginton said.
"You couldn't look at it any other way in terms of him coming home and ... that ambush-style of attack.
"It appears the offender may have had some knowledge of the movements of the victim prior to that."
The man is in a serious but stable condition after being taken to Westmead Hospital and undergoing a number of surgeries, with police yet to speak to him.
A number of the man's relatives and children were inside a property where he was parked outside before being shot.
Police believe there was only one gunman involved who escaped on foot into a park following the shooting.
Anyone with CCTV footage or information about any movements around Niland Crescent at 9pm on Wednesday has been urged to come forward.
Supt Egginton said the victim was not known to police and investigations will examine the motive of the gunman.
Police have not linked the Blackett ambush to any other recent attacks, including a Campsie parking facility shooting on Tuesday night.
Police treated a 27-year-old man with gunshot injuries to his head and chest.
A short time later, police were called to nearby Kingsgrove after reports of a Mercedes sedan crashed into a house and alight, but no one was injured.
Officers have been unable to establish if the incident was connected to the shooting.
Supt Egginton attempted to calm community concerns saying these situations are generally targeted.
"It's always disappointing to see people behaving in this manner and actually resorting to the use of firearms in residential areas where there's children and families around," he said.
Premier Chris Minns on Thursday reassured Sydneysiders that senior experienced detectives in NSW Police were focused on disrupting gun crime and gang violence.
"They're confronting this lawless behaviour in Sydney and it won't go unpunished," he said.
"Just give them time. Breaking up these criminal networks often does mean going after different gangs in a different sequence."
Police Minister Yasmin Catley said officers under Taskforce Magnus, set up to investigate recent place shootings and associated organised criminal activities, have made 217 arrests, with 33 in the past week and 35 firearms seized.
