Gunman's pursuit of 15yo girl 'absolutely abhorrent', police say

In short:

A Sydney father and his daughter were in a ute when a person in a balaclava pointed a gun at them at school pick-up in June.

At the time police said it was not clear whether the gun had jammed, preventing shots from being fired.

A 19-year-old man has been charged with a string of offences, including attempting to discharge loaded arms at a person with intent to murder and installing a tracking device.

A 19-year-old accused of pointing a gun at a man and his teenage daughter at school pick-up in Sydney's west has been charged with attempted murder.

NSW Police were called to a school in Fairfield about 3pm on June 9 after a handgun was pointed at a 44-year-old man and the 15-year-old girl inside a ute.

The man and girl managed to get out of the car and runaway from the gunman, who was dressed in black and wearing a balaclava.

Police said neither were physically injured but were distressed by the incident.

Superintendent Box told 702 ABC Sydney the 44-year-old man was associated with the Alameddine network but had no organised crime links.

"[The man] is aware of the threat that was made against him, and he's taking advice on board for, you know, take precautions for his own safety. We're continuing to maintain contact," Detective Superintendent Jason Box said in June.

He said he was unable to confirm whether the gun had jammed, preventing shots from being fired.

The attempted shooting caused the NSW Department of Education to heighten security at the nearby school.
