Christopher Brilliantes, 21, from Wentworthville, who has been charged with the murder of Patrick Crowe, was denied bail in court today.
Officers arrested Mr Brilliantes and two teenagers - an 18-year-old Auburn man and a 15-year-old Toongabbie boy - at a Parramatta flat about 4.20pm yesterday.
The 18-year-old was charged with concealing a serious indictable offence (murder) and was refused bail.
Mr Brilliantes did not come up from the dock during a brief mention at Parramatta Local Court today.
His solicitor, Louise Jardine, did not apply for bail and it was formally refused by the magistrate, Alison Viney.
The 18-year-old will appear in the same court this afternoon.
The 15-year-old was charged with affray and was refused bail to appear at Parramatta Children's Court today.
A Rosehill boy, 16, was charged with affray yesterday and was granted bail to return to court at another date, police said.
Police will allege the apprentice chef, Patrick Crowe, 22, was involved in a fight with up to five young men as he and two friends were walking on Argyle Street, Parramatta, about 2am on Sunday.
Emergency services found Mr Crowe with a stab wound on the left side of his abdomen and took him to Westmead Hospital. But he died five hours later after emergency surgery.
Mr Crowe's boss, Daniel Pittman, said the "happy-go-lucky" chef was a "very kind person, very easygoing, easy to talk to" and that his colleagues and customers were upset about his death.
Superintendent Robert Redfern said police were looking for a boy in his late teens and three teenage girls, believed to be aged between 15 and 17, who may have seen or spoken to Mr Crowe before his death.
"Come forward and hand yourself in to police so you can be spoken to," Superintendent Redfern said.
He said police from Strike Force Ostend were pleased to have made arrests quickly.
"Nothing we do can bring back Patrick to his family. But it's our hope in making some arrests it brings some comfort to that family in relation to the loss of their son."
The charges came as another man was charged with murder following the stabbing deaths of two men - Phuc Uy Nguyen, 30, and Brian Dao Dung Huynh, 28 - during a fight at Greenfield Parade, Bankstown, on February 1, 2009, police said.
The man was arrested at a unit in Marrickville Road, Dulwich Hill, just before 9.30pm yesterday and was charged with two counts of murder. He was refused bail and will appear in Newtown Local Court today. The man was the third person charged with the deaths, police said.
Police are continuing their investigation into the Parramatta attack and urged anyone with information to phone Crime Stoppers, 1800 333 000.
