Man arrested after dad killed in suspected hit-run in Victoria's east

Police have questioned a man in relation to the suspected hit-run death of a Victorianman on a freeway two hours east of Melbourne yesterday.

A passerby located the 40-year-old Traralgon man's body on the Princes Freeway overpass, which runs over Princes Drive in Morwell, just before 9am.

Yesterday afternoon a 28-year-old Lakes Entrance man was arrested in Bairnsdale.

He was interviewed by police and released pending further enquiries.

Police are still appealing for dashcam footage from motorists who were travelling Traralgon bound on the Princes Freeway between 1am and 9am on May 22.

Detectives suspect the man was hit between 1am, when he was seen walking along the edge of the freeway, and 9am, when his body was found by a passing motorist next to the barrier of the overpass.

"There is every possibility he could've been laying there for eight hours," detective sergeant Mark Amos said.

Amos said the investigation was still in its infancy, but the man may have been hit by a "large vehicle".

"It's really difficult at the moment to place everything... There's a lot of debris up there, there's some marks up there," Amos said.

"He's a son, he's a partner, he's a father," Amos said.

"For a man to be left on the side of the road, alone, in the dark, dying, it beggars belief how people don't just go back and look."

It's not yet known why the man was walking on the overpass, but detectives said it would form a part of their investigation.

Motorists who were travelling on the Princes Freeway towards Traralgon during these times are urged to check their dashcams for evidence of the man or vehicle involved.

"If you've got a business or something in Traralgon, have a look at your CCTV footage," Amos said.

"If you see a car, a truck, four-wheel drive, anything you think might've been involved, let us know.

"What seems to be nothing to you, can be a very, very important piece of a big jigsaw puzzle that we've got here to solve."

Detectives remained on scene for most of the day yesterday, causing the closure of all eastbound lanes of the Princes Freeway between Tramway Road and Village Avenue, as well as Princes Drive.

Those roads have since reopened.
