NSW Police Force is expecting to charge 20-year-old Mert Ney with murder and attempted murder this afternoon, one day after he was arrested, covered in blood, by members of the general public armed with chairs and milk crates in Sydney’s Central Business District, Australia.

Ney allegedly murdered 24-year-old female prostitute Michaela Dunn in an apartment in Clarence Street moments before allegedly plunging a 30cm knife into the back of a 41-year-old woman Linda Bo, who worked at nearby Cosco, outside Hotel CBD in King Street. He then allegedly threatened to stab other people before he was detained in a citizen’s arrest near York Street.

“You would say with some confidence that he went on the street to kill more people, and the fact she’s alive is a miracle,” NSW Police Force commissioner Mick Fuller said today.

Sydney CBD stabber led away

This is what we know about 20-year-old Mert Ney

  1. Mert Ney was reportedly in hospital less than a week ago.

    Ney allegedly ran at his sister Yazel, punched and choked her at the family home in Marayong in Sydney’s western suburbs six days before the Sydney CBD stabbings, according to The Daily Telegraph. Yazel Ney complained to police.
    Ney reportedly went to the emergency department at Blacktown Hospital suffering from a drug overdose. He received treatment and the next day was picked up by an ambulance but reportedly fled out the back of the emergency vehicle.
    Police were later notified. Ney’s family reported him as missing and NSW Police Force issued a Concern for Welfare notice.

  2. A woman’s body was found in an apartment in Sydney CBD.

    A prostitute Michaela Dunn, 24, was found dead with her throat slashed inside her apartment on Clarence Street. Ney is believed to have made an appointment to meet her earlier that day at 1.30pm.
    Ney was allegedly seen on CCTV footage leaving the building at 1.50pm.
    Pedestrians appeared to be running in terror as the bloodied knifeman charged through the street yelling ‘Allahu Akbar’ before he allegedly stabbed a 41-year-old woman.

  3. Details of previous shootings were reportedly found on Ney’s possession.

    When Ney was arrested Tuesday afternoon, authorities allegedly found he was in possession of a USB with details of the Christchurch massacre and mass shootings in the US.

  5. Ney has previously had run-ins with authority.

    Ney was given a conditional release order at Blacktown Local Court after being found in possession of knuckledusters.

  6. It is believed Ney has a history of mental illness.

    Ney’s family reportedly said he had suffered from anxiety, obsessive-compulsive disorder, depression and schizophrenia for years.

  7. The aftermath

    A young woman, who was visibly shaken and declined to give her name and age, spoke to media outside Ney’s home this morning.

    “I saw a lot of news articles saying it was about terrorism, but our family doesn’t practice Islam. Obviously, I know I am dark skinned and I look like I am from the Middle East, that’s going to be the obvious thing. But I’m not Islamic, my mum’s not Islamic, my sister isn’t Islamic, my dad is probably an atheist. We’ve got nothing to do with Islam at all,” she said, The Guardian reported.

    “Using religion as an excuse it’s not correct.

    “In the past week, it’s obvious he’s had a steep descent into insanity,” the woman claimed. “I think he was meant to take medication … it is clear he was mentally ill but I’m not too knowledgable because as I was saying, we’ve had an estranged relationship.”

    Ney’s mother had not been eating or drinking since the incident, the relative said.

    “She’s sick. We had to go to the doctors last night. I wish there was a way for me to make it all better for her, but I can’t. I can’t make it better for anyone else. I wish I could. I just want to say sorry to the family, sorry a million times.”

    “(I don’t want) to speak to him again. I’m afraid of him.

    “If this happened to a family member you knew, you wouldn’t want to go near them, would you? Something so despicable. I feel shocked, angry, disgusted. I hate my last name.”
