Two men who suffered injuries include a 30-year-old Briton, who is said to be in a critical condition. The suspect is in custody in a hospital and is yet to be charged over the knife attack in Queensland, media reported. “Investigators will consider whether mental health or drug misuse factors are involved in this incident,” he said. Gollschewski said the accused used the Arabic phrase “Allahu Akbar” both during the attack and his arrest. “While this data will be factored into the investigation we are not ruling out any motivations at this stage, whether they be political or criminal,” he said. “We’re working closely with our partner agencies to make sure if there is any indication that it has an extremist slant, or this person had been radicalised, we can discover that,” he said.
