Diamond Creek man Andrew William Lee has been charged with murder over the death of teenage footballer Patrick Cronin who was allegedly king hit in a wild pub brawl on the weekend.

Mr Lee, 33, appeared briefly before a bail justice in an out-of-sessions hearing on Tuesday night and was remanded in custody to appear in the Melbourne Magistrate's Court the following morning.

Dressed in a black hooded jumper, Mr Lee listened quietly as the charge of a single count of murder was read out to him, only responding "yes" when asked if he understood.

Detective Senior Constable John Midson told the hearing Mr Lee had participated in a police interview but had declined to comment.

Mr Lee is believed to have walked into the West Melbourne police station with a lawyer on Tuesday after police had earlier released images of a man they wished to speak to about the death.

Mr Cronin,19, died on Monday after he was taken to hospital early on Sunday with a critical head injury sustained in a violent brawl at the Windy Mile hotel in Diamond Creek.

The violence had erupted at the Main Road pub around 11pm on Saturday night. Mr Cronin was a popular young footballer who had played for the Lower Plenty Football Club earlier the same day.

Detective Senior Constable Midson reading the police summary out, said Mr Cronin had been "acting as a mediator" when he was fatally wounded.

His family had made the gut-wrenching decision to turn his life support off after they had made plans to donate all of his organs except his heart.

Just hours after Mr Cronin's death, Victoria Police had released grainy CCTV images of a man they wanted to speak to in relation to the alleged assault.

On Monday, Lower Plenty Bears president Grant Barden denied there had been a brawl between two football clubs before Mr Cronin was punched.

The investigation is still ongoing
