Australian police are searching for two young Irishmen after a crash in which two other young men were seriously injured.
The crash happened in the Sydney suburb of Chifley.
Eye-witnesses said a car travelling at speed crashed into a parked Toyota Hiace van leaving two men trapped in the car.
CCTV footage shows the driver of the car jumping out of the wreckage, surveying the scene before fleeing on foot.
One of his passengers also fled on foot a short time later.
Emergency services including police and ambulance personnel arrived on the scene afterwards.
