A young man has been charged with murder over the death of another man at serviced apartments in Sydney's CBD.
The 20-year-old man was arrested after the 43-year-old man died at the Haymarket apartment building in the early hours of Easter Sunday.
He was scheduled to appear before Parramatta Bail Court on Monday but the court was told he had been transported to St Vincent's Hospital from police custody.
His case is expected to be mentioned in a Sydney court later this week.
Residents told police they had heard a "melee" or a "wrestle" taking place in the hallway outside their doors on the 13th floor of the Castlereagh Street apartment tower at about 3am on Sunday.
"It's made enough noise to rouse the neighbours, who have contacted police," Detective Acting Superintendent Paul Dunstan said on Sunday.
The men were in one of the apartments on the 13th floor before their altercation spilled into the hallway.
The incident started with punches then escalated into a wrestle but no weapons were used, Supt Dunstan said.
Neighbours and emergency services tried to resuscitate the older man in the hallway, to no avail.
Police are seeking no other people over the incident.
