An assault spree in Kings Cross that resulted in the death of Thomas Kelly helped police locate the young man they believe is responsible for his murder.

Seven Hills man Kieran Loveridge, 18, was arrested at about 7.30pm yesterday at Belmore sports grounds and charged with Mr Kelly's murder.

He was also charged with assaulting three other males during an alleged rampage along Sydney's nightclub district in Kings Cross.

Mr Kelly was walking in the precinct with his girlfriend and talking on his mobile phone when he was king hit in an unprovoked attack.

He struck his head on the ground after collapsing and died two days later when his parents turned off his life support.

Loveridge faced Burwood local court this morning but did not apply for bail.

He is expected to appear again next week.

Police have not ruled out further arrests.

"It is likely that should there be sufficient evidence, we'll put people before the court," state crime commander Mal Lanyon told reporters in Sydney on Thursday.

"However, I can say that I'm satisfied the 18-year-old male that was charged last night was the only person involved directly in the assault of Mr Kelly."

After yesterday's arrest, police executed a search warrant at a home and seized a number of items of clothing.

Detectives reviewed a great deal of CCTV footage which helped in their arrest.

The other victims came forward prior to Mr Kelly's parents making a public plea for witnesses.

None of the victims was known to the accused and police would not comment on a possible motive for the attacks.

Mr Kelly was attacked minutes after the first victim and the two other victims were assaulted a few hours later.

Mr Lanyon would not comment if the accused was under the influence of drugs or alcohol, or if he was refused entry into a Kings Cross nightclub.

He had been under surveillance for at least two days and declined to be interviewed after he was taken into custody.

Senior police have not spoken directly to the Kelly family, who will attend a memorial service tomorrow at The King's School Parramatta where Mr Kelly was a student.

"I'm sure that they were relieved when they heard the news," acting commissioner Catherine Burn told reporters.

Police would not comment on whether Loveridge's DNA was acquired prior to his arrest or if he had a criminal record.

Mr Kelly's death has sparked renewed calls for compulsory 3am closing times and 1.30am lock-outs to help curb the violence in the notorious nightclub district.

In a community forum in Sydney on Tuesday night, Hospitality Minster George Souris announced that every bar and club in Kings Cross would be audited to try and stamp out anti-social behaviour.
