A paramedic is in a stable condition after being struck by a car at Sydney's Eastern Creek raceway.
The 54-year-old was carried on the bonnet of the vehicle for about 40 metres before falling to the ground where he sustained leg and head injuries.
Police will allege the private paramedic intervened in an altercation between a 44-year-old man and a 32-year-old woman, who are known to each other, at the raceway on Saurday afternoon.
The man then got into a Ford Falcon XR8 and drove towards the paramedic and failed to stop.
Police engaged in a pursuit after the Falcon was later spotted on Ettalong Road at Greystanes, which was terminated a short time after due the manner in which the car was being driven.
Polair followed the vehicle into a car park in Seven Hills where the man was arrested.
He will appear in Parramatta Bail Court on Sunday charged with multiple offences including stalking and intimidation, common assault and dangerous driving occasioning grievous bodily harm.
The paramedic was treated at the scene before being taken to Westmead Hospital in a serious but stable condition.
