Authorities responded to a residence on Aberdeen Street in Bossley Park early yesterday morning, around 6:30 am, following reports of gunfire.

Upon arrival, officers discovered that several shots had been discharged into the home and at a vehicle parked out front. These shots were fired from an Audi sedan, which quickly fled the scene afterward.

The elderly couple residing in the house, both in their 80s, fortunately escaped harm.

This incident marked the second time in two days that the house was targeted by gunfire. Law enforcement officials suspect that the homeowners are innocent, with no apparent ties to any criminal activity.

Shortly after, police found the Audi abandoned after it had crashed at a nearby intersection of Mimosa and Prairie Vale Road.

The individuals inside the vehicle reportedly fled the scene on foot.

During a search of the sedan, police allegedly seized an automatic firearm believed to be an AK-47.

A crime scene was established at the home and the place of the crash.

At 1.30pm yesterday, police executed a search warrant at an address on Woodville Road in Fairfield West and arrested a 22-year-old man.

The man was taken to Cabramatta Police Station and was charged with firing a firearm at a dwelling, as well as organised crime activity and participating in a criminal group.

He was refused bail and faced court today.

During the Fairfield West search, police said they also found a shortened calibre rifle, ammunition, and several mobile phones.

About 6.15pm yesterday, officers stopped a vehicle on Camden Valley Way in Leppington and arrested a 16-year-old boy.

The 16-year-old was refused bail.

Detectives executed a search warrant at an address on River Mint Avenue in Leppington about midnight, seizing ammunition and clothing.
