A friend of the witness also posted: "He almost hit us speeding away.
"We were coming up to redhill ish dominion road, NEK MINUTE. He was drifting around the 50km corner going 100km minimum." Police last night confirmed that a car failed to stop for police about 11.50am yesterday.
"Police followed the vehicle for a short time until the vehicle stopped and reversed into the patrol car causing significant damage to the offending vehicle.
"The offending vehicle then sped off again," police said.
Officers identified the driver so did not chase the car.
They did not believe there was a child in the car.
"The Eagle helicopter, a dog unit and other police [tried] to locate him but he was not found. Enquiries are ongoing."
