A South Australian man in a four-wheel drive has struck a police officer before trying to flee the scene on foot and being hit by a car himself.
Police say the incident began just after 4pm on Monday, when a 4WD struck an officer on Merlin Road in Adelaide's Fulham Gardens.
The officer suffered serious injuries and has been taken to hospital.
The driver fled the scene and dumped the 4WD near Grange Road before trying to run away.
He was confronted by police and ran into the path of oncoming traffic, where he was struck by a car.
The man suffered non-life threatening injuries and is under police guard at Royal Adelaide Hospital.
