A man has been charged with indecently assaulting stabbing victim Morgan Huxley on the night he was killed in his Neutral Bay unit, a Sydney court heard on Thursday.
Police have charged Daniel Jack Kelsall with breaking into Mr Huxley's unit with the intention of indecently assaulting him in the early hours of September 8 last year.
Homicide detectives will allege the 21-year-old touched Mr Huxley's penis on the night he was stabbed to death, according to fresh charge sheets tendered to Central Local Court.
Mr Kelsall chose not to appear to face the two extra charges but was represented by lawyer George Breton.
Mr Breton said his client was "doing well" and was "settled" in custody.
Mr Kelsall is accused of killing Mr Huxley by stabbing him up to 28 times in the bedroom of his Watson Street unit.
Mr Huxley, a north shore businessman, was found barely alive by his Irish flatmate Jean Redmond.
Paramedics were called but he died a short time later.
Mr Huxley had spent the day at a friend’s engagement party and was last seen walking out of the Oaks Hotel after a nightcap about 1.30am.
Security footage last captured him talking to a man wearing chef's pants at a busy intersection less than 150 metres from his unit.
Police arrested Mr Kelsall after a four-week investigation under intense media scrutiny and speculation.
Homicide detectives swooped on the Kelsall family’s Spruson Street unit at 9.30am on Tuesday, October 8, last year.
The 20-year-old dish hand was dressed in a brown, hooded jacket and clutched a worn paperback copy of the fantasy novel Magician as police took him into custody.
He was refused bail and, in March this year, police laid two offences regarding child abuse material.
Police will allege they found child abuse images on a laptop and a hard drive that was seized from his unit when he was arrested.
Homicide detectives say that, on the night of the alleged murder, Mr Kelsall struck up a conversation with Mr Huxley at a set of traffic lights in front of Thai restaurant Stir Crazy.
He then followed Mr Huxley home.
Mr Kelsall was contracted to clean dishes after hours at the Sydney Cooking School, a business that is less than 100 metres from Mr Huxley’s unit.
He had worked in the hours leading up to the alleged murder.
Mr Kelsall did not apply for bail on Thursday and it was formally refused by magistrate Greg Grogin.
His matter is again due in court June 12.
