Witnesses said they heard up to four shots fired at the Minchinbury home around 9pm yesterday.
Multiple bullet holes can be seen peppered across the walls and windows of the family’s living room.
There were four adults and four children inside the home at the time, none of whom were injured.
“They were just calling out and saying ‘they got shot at, they got shot at,'” a witness said.
Police said the family was in the living room at the time and was lucky not to be hit by the bullets.
“They were in hysterics they would have been sitting in the room where they got the shots,” another witness said.
Chief Inspector Paul Tickner said it was a “seriously irresponsible act.”
Police believe some of the people in the house were the target of the attack.
“We believe some of the people in the premises and potentially some of the teenagers that were at the premises at the time were probably the targets of these shots,” Chief Inspector Tickner said.
“There were some people that live at the premises or were at the premises that have some affiliations with some gangs out in Western Sydney.”
Detectives this morning have recovered CCTV vision that shows a small grey four-door hatchback seen in the area at the time of the shooting.
Police believe there were at least two people in the vehicle.
Anyone with information is urged to contact police.
