Dashcam footage emerges of Porsche speeding down Eastern FreewayDashcam footage of a Porsche driving erratically on Melbourne's Eastern freeway a month before four police officers were killed is now under investigation.

Victoria Police Chief Commissioner Graham Ashton said the black Porsche 911 caught on film zooming down a 100km/h section of the freeway on March 21 looks similar to the vehicle allegedly involved in a crash that killed four officers last night.

"The investigators have got that footage. Just to my eye, it looks pretty similar," Comm. Ashton said.

"We are still looking at that footage but it does appear to be a very similar vehicle."

The dashcam owner reported the incident to police the day after it was recorded.

Police said today the driver of the Porsche involved in the fatal highway crash has an extensive criminal history.

He is due to turn himself in to a police station this morning.
