Two people allegedly flee scene after two boys killed in south-west Sydney car crash

Two boys aged between 10 and 15 have died in a car crash in Sydney’s south-west, while two other people were seen running away from the wreckage.

Emergency services were called to Ashcroft after reports of a crash about 10.50am on Monday.

Police also want to speak to the rider of a trail bike which was seen travelling on the street at the same time as the crash.

CCTV footage from the scene shows the bike riding on to the grass moments after the crash.

Assistant Commissioner McFadden said it was unclear what, if any, role the bike may have played in the incident but that it was an “active line of investigation”.

Search for those who fled scene

Police dogs have been used to scour the bushland near Cabramatta Creek at Magee Street and Maxwells Avenue in the search for those who left the scene.

The assistant commissioner said inquiries into how the crash occurred and the state of the remaining occupants of the car are ongoing.

“They just need to present themselves to a police station so we can engage with them and they can assist us with the inquiries and work out how this tragic situation unfolded,” he said.

“The driver is ultimately responsible for themselves, the passengers and the others on the road.”

A crime scene was established and the road cordoned off.

The scene will be forensically examined by the crash investigation unit.

Assistant commissioner McFadden said speeding was a “selfish” act that had played a large role in more than 100 deaths this year.

“The community should be outraged and the wider community should take stock that this is a result of speeding,” he said.

“This represents 300 lives lost on our roads so far this year … and our estimate is around 40 to 50 per cent of those lives lost, speed is a direct contributing factor.
