A 21-year-old man has been dramatically arrested after going on a stabbing spree in Sydney’s CBD.

The attacker is accused of killing a woman in an apartment, before randomly attacking members of the public, including a 41-year-old woman who was stabbed in the back.

Dramatic vision, obtained by 7 News, shows the alleged attacker, covered in blood, being restrained by citizens and emergency services workers.

He was armed with a large knife.

It’s since emerged the alleged offender, Mert Ney, has a long history of mental illness and drug abuse, and is known to police.

Police do not believe the incident was terrorism.

“What we can conclusively say is that the male offender was on his own,” NSW police said.

“The threat to the community has been negated.”

The alleged attacker was filmed climbing a moving Mercedes-Benz, before screaming “shoot me” repeatedly as people tried to bring him under control.

2GB reporter Tamara Wearne spoke with Tom Elliott from the scene.

“He held the knife in the air and started screaming,” she said.

Police have seized a phone and USB stick from the attacker which contained information relating to recent violent acts of white supremacy overseas.
