Sydney stabber Mert Ney pleads guilty to murder

A man who stabbed a young sex worker to death before going on a knife rampage in Sydney's CBD has pleaded guilty to murder.

Mert Ney, 22, sent the city into lockdown and had to be detained by bystanders after he ran with a bloodied knife through the streets in August 2019.

Just hours earlier he had paid for Michaela Dunn to meet him at an apartment for sex but once she arrived he pulled out a knife and murdered her.

Ney faced Central Local Court on Tuesday where he pleaded guilty to murdering Ms Dunn, stabbing the second woman Linda Bo and a third incident related to an assault on his sister.

When asked to enter a plea he replied: 'Ah, guilty'.

Ms Dunn (pictured), 24, had been lured to a hotel room on Clarence Street, in Sydney's CBD 

Shocking footage taken in the moments after show him stabbing another women in the back, before screaming 'Allahu Akbar' as he held his knife aloft.

Police had received a call from worried CBD workers about 2pm of a man wielding a knife on York Street.

When they arrived they found Ms Bo, 41, in the lobby of a nearby hotel suffering stab wounds.

As Ney continued to roam the streets, several witnesses eventually rushed him and pinned him to the ground using a milk crate.

About 3.15pm police discovered Ms Dunn's body in the Clarence Street apartment.

NSW Police soon confirmed the two stabbings are linked and that they have taken Ney, who has a history of mental health issues, into custody.

Despite him yelling out the well known Islamic extremist phrase, he was not found to have any links to terrorism.

As he entered his guilty plea in court on Tuesday, six other charges of attempted murder, wounding with intent to murder and possessing child pornography were withdrawn. 

He will face the NSW Supreme Court on December 11.
