Sydney crash driver 'had drugs, cash'

A 22-year-old driver who crashed into two empty parked cars in northwest Sydney was allegedly found with suspected cocaine, prescription drugs and $16,000 in cash.

The man was treated for minor injuries after his Volkswagen Golf flipped on its side in the crash at Winston Hills on Tuesday.

Police officers allegedly found bags of white powder, a container of Xanax and the cash in his bag.

The man also allegedly threatened a constable at Castle Hill Police Station.

He is due to face the Parramatta Local Court on Wednesday charged with drug supply, dealing with proceeds of crime, possessing a restricted substance, intimidating a police officer, driving while suspended and negligent driving.
