Cronulla 'hero' Alex Roberts helped chase alleged Sydney CBD attacker

A man from Cronulla has been described as one of the 'heroes' who helped chase a knife wielding man who allegedly went on a stabbing rampage in Sydney's CBD on Tuesday afternoon.

Sutherland Shire's Alex Roberts was among the men who were praised for their exceptional efforts after Mert Ney, 20, allegedly killed a woman in an apartment and wounded another, before running through the streets with a large knife.

Mr Roberts, Lee Cuthbert and Paul O'Shaughnessy, were among those who helped detain the man before police arrived.

Mr Roberts was at work when drama unfolded. He along with others, chased Ney before catching up with him. He says although the experience was frightening, he did not hesitate when he and others saw the incident occur.

"We were all in the office and we saw the commotion downstairs and we all just legged it down and just chased. No...I didn't really think, I should have..." he told The Sydney Morning Herald.

NSW Police Minister David Elliott praised all who went "well and truly above the call of any citizen".

Police said the alleged attacker did have some ideologies in relation to terrorism and confirmed that he had recently self-admitted himself [to a facility] prompting subsequent mental health assessments.

Late Wednesday afternoon police identified Michaela Dunn, 24, from Sydney's inner west, as the woman who died in yesterday's violent rampage in the CBD.

Ms Dunn, a former student of the University of Notre Dame, was found with fatal stab wounds to her throat in an apartment on Clarence Street.

In a short statement police said Ms Dunn's family appreciated "the support offered by the community" but "requested their privacy at this difficult time".

The 24-year-old is a former student of Rosebank College in Five Dock, where she graduated in 2012. She then went on to study marketing and public relations at the University of Notre Dame in Sydney.

Her mother, Joanne Dunn, said her daughter was well-travelled, loving and from a beautiful family in Sydney's suburbs.

She had travelled to the United States and Sri Lanka in the past year, according to her social media accounts.
