Driver arrested after passenger's death

A driver who allegedly abandoned his fatally wounded girlfriend at the scene of a car crash has been caught by police.

Hussain Wraydeh, 39, was arrested on Wednesday, more than a week after the crash at Punchbowl, in Sydney's south west.

Superintendent Stuart Smith said Wraydeh is being questioned at Bankstown Police Station in relation to several matters, including the crash and a large number of credit cards found in his possession.

Police say Wraydeh was driving a Mitsubishi Evo when it collided with a Honda SUV on Warwick Street shortly before 11am on August 7.

Wraydeh allegedly fled the scene, leaving his dying girlfriend, 38-year-old mother-of-two Georgina Abdallah, in the passenger seat.

Ms Abdallah died later that night in hospital.

The 45-year-old driver of the Honda SUV was taken to hospital and treated for minor injuries.
