A man accused of killing a 24-year-old sex worker and stabbing a 41-year-old woman in the Sydney CBD has been charged with a string of offences including murder and attempted murder.
Mert Ney, 20, allegedly killed Michaela Dunn, 24, in a Clarence Street apartment on Tuesday before allegedly stabbing Linda Bo, 41, in the shoulder at the Hotel CBD.
He was later filmed running through the city streets brandishing a bloodied kitchen knife before being restrained by onlookers and arrested.
Ney was taken to Royal Price Alfred Hospital for treatment and was transferred to Surry Hills Police Station for questioning just after midday on Friday.
The 20-year-old was later charged with murder, attempted murder, wounding with intent to cause grievous bodily harm, intentionally choking with recklessness and common assault.
He is due to appear before Parramatta Bail Court on Saturday.
Investigators have been trying to piece together why Ney - who had a history of mental illness - launched the attack.
NSW health authorities are reviewing his care and treatment in the lead up to the alleged attacks.
Ney was allegedly carrying a USB stick with information about recent mass casualties in New Zealand and the United States and could be heard on video footage shouting "Allahu akbar".
NSW Police have not classed the attack as a terrorist incident and have not identified any links to terrorist organisations.
