Police step up investigation of M4 crash

Police are appealing for more witnesses to come forward with information about a multi-vehicle crash on the M4 in January that caused the death of a Doonside motorcyclist.

Brett Griffin, 35, died at the scene at about 12.35pm on January 18 when a motorbike and several vehicles crashed near the intersection of Centenary Drive at Homebush.

Police believe the motorcyclist was thrown from his Triumph 1000cc motorbike after striking a concrete barrier, then hit by a Mitsubishi Lancer and run over by a Toyota Hilux. Two other vehicles also collided trying to avoid the first crash.

Metropolitan Crash Investigation Unit senior constable Janine Norris said police have taken statements from several witnesses to the crash but are ‘‘keen to speak with the driver of a black vehicle travelling east along the M4 at the time of the crash’’.

“The crash occurred on a very busy road during a busy time of the day and we are hoping that someone can help police with this investigation and provide any information – no matter how insignificant you may think it is’’

“I urge the driver of the black vehicle to come forward as they may be able to provide crucial information about the events leading up to the impact.’’

Anyone with information can contact Crime Stoppers on 1800 333 000 or report via https://www1.police.nsw.gov.au/.
