Mandurah Detectives are still hunting for a driver who ploughed into a man and woman, leaving them with serious injuries.
The victims, a 38-year-old man and 36-year-old woman, along with two young teenagers were in a white Mitsubishi Triton ute when they were involved in a minor crash with a small silver car on Mandurah Road near Park Road in Greenfields around 10.25pm on Thursday, September 26.
"The vehicles followed each other through various streets including Mandurah Terrace, Henson Street, and Anstruther Rd, until the Mitsubishi Triton pulled over on Crawford Street in Mandurah," a WA Police spokesperson said.
"Two occupants of the Triton exited the vehicle and walked towards the silver vehicle. The silver vehicle did not stop, hitting both people."
The pair suffered serious injuries and were taken by ambulance to hospital.
