Numerous witnesses had to confront a frenzied man with a foot-long knife, who was screaming "Allahu Akbar" and threatening people in Sydney on King and Clarence Streets.
Photos and videos, shared in social networks show a man with a chair, fighting back the assailant, and then a group of people who managed to restrain the criminal by pinning him down with chairs and putting a crate over his head.
The knife-wielding attacker is now in custody, while the Australian police is investigating a stabbing attack that had occurred nearby before the incident.
