A few minutes later, the 4WD crashed into a parked car at Quick Street, Rozelle. But the driver got away, and as at 7.30am on Sunday had not been found.

Sniffer dogs, helicopters as well as the public order and riot squad were used on Saturday night to attempt to locate the person or persons who fled from the 4WD.

Both injured officers have been released from hospital. One was treated for a head injury, and the other for lacerations.

The incident will be investigated by a critical incident team, with that investigation also subject to independent review.
