A 22-year-old man who was attacked during a brawl on Victoria's Mornington Peninsula overnight has died.
Police say the victim died in the Alfred Hospital in Melbourne at 4pm (AEDT).
He was set upon by a group of men on Rye's main shopping strip, across the road from the pier, early this morning.
Detective Sergeant Sol Solomon says he is dismayed by the attack.
"It's just another one of these typical very tragic incidents where we have young peoole fuelled by alcohol behaving aggressively and violently on the streets," he said.
Police are still trying to find the attackers.
Detective Sergeant Solomon says the victim was hit on the head and fell onto the footpath.
"It's a short assault, very aggressive, hostile, violent - it's the only way I can put it.
"It appears to be totally unprovoked."
Another man has been treated at the Frankston hospital for a suspected broken jaw.
Witness Jack Williams says he could not believe what he was seeing.
"I felt like I needed to step in but the police started rocking up real quick," he said.
Mr Williams says he fears the violence has damaged the town's reputation.
"I mean, it's a good town but now all this is going to be on the news and in all the papers, it's just another thing for New Year's Eve, there's always something down here for New Year's Eve," he said.
"A lot of tourists like to come down because it's a good spot.
"It just sets a bad reputation for here."
Homicide Squad detectives have taken over the investigation and are appealing for witnesses to come forward.
