NSW police commissioner Mick Fuller speaks to the media in Sydney about the arrest of a 20-year-old man who allegedly went on a stabbing rampage in Sydney's CBD. The western Sydney man was arrested on Tuesday after he allegedly stabbed a 41-year-old woman at the Hotel CBD about 2pm and then tried to stab countless others as he wandered the streets. The body of a 24-year-old woman was subsequently discovered at a nearby apartment. Fuller says the USB drive contained details of 'other mass casualties and mass deaths around the world', and that the man has a history of mental illness and is known to police but his past was 'unremarkable compared to the gravity of the crimes that he committed'
