Major Crash officers are investigating a crash which left a 23-year-old woman and a 23-year-old man with serious injuries yesterday afternoon.
The two were the rear passengers in a Holden Commodore sedan being driven by an 18-year-old man of Bluff Point.
Police say the car travelled onto Edward Road from Arthur Road when the rear tyre blew and the Commodore lost control, rolling several times in a nearby paddock.
This car was travelling in company with a Holden Commodore ute, and police will investigate whether the Commodore sedan was recklessly driving prior to the crash.
Both injured passengers were taken to Royal Perth Hospital where they are being treated for head injuries.
Anyone who witnessed either is asked to call Crime Stoppers on 1800 333 000.
