Sydney police received a call at about 2PM today of a man wearing a balaclava and wielding a large butcher’s knife in the vicinity of King St. He shouted “Allahu Akbar” and challenged police to “fucking shoot me in the head”. He has since been identified as a 21-year-old man from Marayong. The man stabbed a 41-year-old woman in the back in what appears to be a random attack. Three members of the public engaged and restrained the “clearly dangerous” man, using a chair and a milk crate, near Wynyard railway station. Emergency services and police responded and the man was soon arrested. Then police discovered the body of a 21-year-old woman in an apartment on Clarence St. The man was found to have terrorist information on a USB drive about mass casualty crimes overseas, including in North America and New Zealand. However he has no known links to terrorist organisations. Police said the man had a long history of mental health issues, and they were investigating reports he absconded from a mental health facility in recent days.
