Police investigating whether three overnight shootings and two car fires across Sydney were linked

Police are investigating whether three shootings involving a home, a caravan and a business in Sydney's south-west overnight were linked.

The first shooting took place just after 11.15pm when shots were fired at a house in Margaret Street, Fairfield, before a dark-coloured SUV left the scene.

A man and a woman, both aged in their 20s, were at home at the time and were uninjured.

At about 11.55pm, police were called to Aberdeen Street in Bossley Park after a single shot was fired at a caravan parked on the street before a white Audi left the scene.

The occupants of that home were a couple aged in their 80s.

No injuries were reported.

Shortly before 3am, police were called to McIlwraith Street in Wetherill Park after shots were fired at a towing business before a car believed to be a black SUV or ute left the scene.

No injuries were reported.

"This sort of stuff just won't be tolerated," Deputy Superintendent Craig Middleton from NSW Police said.

"Anyone who chooses to fire a firearm in a public place, (is) extremely reckless and dangerous."

Police are investigating whether the incidents are linked, or if there are connections to two overnight car fires at Kings Langley and Lalor Park.

One of the cars matches the description of the vehicle used in the shootings in Fairfield and Wetherill Park.

Anybody with information is urged to contact Crime Stoppers on 1800 333 000 or online.
