Sydney stabbings crate heroes celebrated with memes

The heroes of the Sydney stabbing have been celebrated online, after they were able to subdue a lone knifeman terrorising bystanders in the CBD yesterday.

Mert Nay, 21, was shown in alarming video wandering the streets of Sydney's CBD about 2pm yesterday, yelling "Allahu Akbar!" and taunting bystanders to shoot him in the face, as he waved a large butcher's knife at them.

Video shows Mr Ney being chased by a group of brave bystanders, some of whom had armed themselves with cafe chairs and milk crates.

During his rampage, Mr Ney allegedly stabbed a woman, 41, in the back, at the Hotel CBD, before trying to stab at countless others, as he wandered the streets. Police also believe Mr Ney was involved in the death of a woman, 21, whose body was found in an apartment on Clarence Street shortly after the attack.

The rampage was stopped by a group of citizens, who detained Mr Ney by holding him down with a chair and a milk crate, near Wynyard Station.

The police Superintendent Gavin Wood described the men involved in detaining the alleged attacker as the "highest order heroes", saying it was hard to know how many lives they saved yesterday.

Online, the heroic actions of the group of citizens who chased down and detained the alleged attacker have been praised, with a series of memes celebrating the ingenious use of a milk crate and chair to disable the knife wielding man.
