The Major Crash Investigation Section is again asking for witnesses to come forward concerning a fatal traffic crash, which claimed the lives of four young boys in Ravenswood on June 27.

The four were the occupants of a Holden Commodore sedan which contained five people, being driven west along Pinjarra Road in Ravenswood at around 10pm.

The car failed to negotiate a left hand bend, causing it to lose control and crash into a metal light pole.

Investigations into this fatal crash are ongoing by the Major Crash Investigation Section.

Police have confirmed that the surviving occupant of the vehicle was a passenger, and not the driver of the Commodore.

The driver of the vehicle was one of the juvenile males who tragically died in this incident.

Anyone with further information regarding the crash is asked to contact Crime Stoppers on 1800 333 000.
