A teen trio have been charged with the murder of Melbourne man Paul Costa, who was found dead in a designer suit at a suburban park.
A passer-by found the 43-year-old at Brunswick West on July 3 wearing a Zegna suit and shoes, and on Thursday detectives arrested two males, aged 17 and 18, at Thomastown.
At the same time, a 16-year-old boy was arrested at Newcastle in NSW and he is expected be extradited to Victoria on Friday.
The victim's family say he was a gentle man and thought he may have been on a date the night he was killed.
"He had a heart of gold, I don't know anyone who'd want to hurt him," his sister Sandra Di Giorgio told reporters previously.
The 18-year-old Thomastown man is due to face court on Thursday, with the 17-year-old to appear in a children's court.
