A teenage boy and two men have been charged over the death of a Melbourne grandfather after a dispute erupted over Christmas Day fireworks.
Anthony Clark, 50, was hit on the head as a fight broke out outside a Mooroolbark property just before 11pm on December 25 last year.
The Mooroolbark grandfather was placed in intensive care before his family gave permission to switch off his life support.
"He's brain dead. It's heartbreaking," the victim's brother-in-law told 3AW at the time.
Three males, aged 17 to 19, were arrested on Thursday morning.
The trio were interviewed by police, with a 19-year-old Yellingbo man and 17-year-old Mooroolbark boy charged with manslaughter.
A 19-year-old man from Glen Waverley, was slapped with assault charges.
The two 19-year-olds will appear in Melbourne Magistrates Court and the 17-year-old will front a children's court, all on Monday.
The stepdaughter of Mr Clark has alleged a group of young males armed with baseball bats attacked her stepfather and mother after a dispute over fireworks.
Sue Clark, 60, suffered minor injuries in the Christmas brawl and needed hospital treatment.
Two days after the initial attack, another fight broke out at the same property.
Four people, understood to be relatives of Mr Clark, were arrested and charged with affray.
Mr Clark had nine children and six grandchildren.
