Four police officers killed in Melbourne highway truck crash

The Porsche driver who fled the scene of the accident that killed four Victoria police officers in Melbourne has made contact with police, Chief Commissioner Graham Ashton said.

The crash happened on the Eastern Freeway near Chandler Highway at about 5.40pm Wednesday after two officers pulled over the Porsche 911 for speeding and decided to impound the vehicle.

After two other officers were called to assist, a large refrigerated truck from a poultry company drove at 100 kilometres per hour into the four police officers.

Commissioner Ashton said they believed the driver of the Porsche was uninjured and fled the scene on foot.

A male truck driver was taken to hospital with non-life-threatening injuries. The police officers, including two male constables, one female senior constable and one male senior constable, were killed.

On Thursday morning, Commissioner Ashton said the Porsche driver had an extensive criminal history and tested positive for “some type of drug” after police intercepted him.

Investigators had since made contact with the person.

“There have been some images placed on Facebook that appear to have been taken by this individual at the scene, before he has left the scene,” Commissioner Ashton said.

“Some of those photographs were circulating last night online.

“We are talking to Facebook this morning about removing them.”

The incident is being investigated by the homicide squad and the major collision investigation unit.
