Investigators believe a vehicle involved in this morning's fatal M4 crash may have left the scene before speaking with police.
A 36-year-old Wentworthville man died at the scene when his citybound utility was struck by a light-rigid truck carrying beer kegs, about 5.50am (Thursday 9 May 2019), at the Church Street off-ramp at Mays Hill.
It's believed 11 vehicles were involved in the crash, with five people taken to hospital for treatment to various injuries; however, only 10 vehicles stopped.
While investigators are not suggesting the driver of the unknown vehicle caused the crash, they do believe they may have information which may clarify the circumstances surrounding the incident.
All drivers have been taken to hospital to undergo mandatory testing.
Crash Investigation Unit Commander, Inspector Katie Orr, said police wanted to speak with the driver of the 11th vehicle to find out what they may have seen at the time of the crash.
"We want to speak with this driver to find what they know about the events leading up to the crash," Inspector Orr said.
"We also want to speak with any drivers who may have witnessed the crash and left the area or have relevant dash-cam footage."
All citybound lanes have now re-opened after being disrupted for more than five hours.
