A man driving colleagues home after finishing work at a Sydney restaurant has been charged after his car struck a tree, killing his female passenger and injuring two others.
The 23-year-old, who also suffered minor injuries, was arrested shortly after the crash early on Tuesday and subsequently charged with dangerous and negligent driving causing death and injury.
Police say the workmates were on their way home when the car lost control and smashed into a tree on Mona Vale Road near Forest Way about 1am.
A 27-year-old woman in the back seat died at the scene.
Another woman, 22, and a 19-year-old man were injured and taken to Royal North Shore Hospital where they remain in a stable condition.
The driver underwent mandatory drug and alcohol testing in hospital before he was arrested and taken to Manly Police Station for questioning where he was later charged.
Chief Inspector Phil Brooks says police are investigating if speed was a factor.
"This was a group of young people of Indian descent that we believe had finished work at a restaurant nearby and were travelling home after their evening work," he told reporters on Tuesday.
"To find a 27-year-old female deceased at the scene certainly highlights the very tragic nature of this event."
Police are attempting to contact the family of the deceased via the Indian consulate, Insp Brooks added.
The driver is due to appear in Manly Local Court on Wednesday.
