A police officer was allegedly beaten by an unlicensed driver during an incident in Western Australia.
The officer was conducting radar checks with his police partner on the Great Eastern Highway in Greenmount on Thursday when he was hit by a 1982 Ford ute.
Then the driver fled the scene, which led to a chase.
The officer, who is in his fifties, was left unconscious on the ground and taken to hospital with serious injuries.
The Great Eastern Highway was closed and turned into a crime scene.
Police later arrested a 34-year-old man at his home in Mount Helena in connection with the alleged hit-and-run incident.
He spent a night in police custody before being charged with seven offenses including not providing assistance.
Greenmount area residents say the stretch of highway is well lit but the part with a slight incline incline can be dangerous and a potential blind spot, especially when traveling at high speed.
