Assistant Commissioner Anthony Cooke said he was known to police and was 'very clearly' suffering from mental health issues. Six shoppers were killed during the attack at Bondi Junction's Westfield in Sydney east yesterday afternoon before Cauchi was gunned down by a hero female police officer. A nine-month-old baby girl remains in ICU in a serious but stable condition. The knifeman behind the horrific stabbing rampage in Sydney which left six people dead has been identified as 40-year-old Joel Cauchi 'We know that shortly after coming to Sydney, he took possession of a storage facility that has been identified,' he said. 'We are continuing to work through the profiling of the offender but very clearly to us at this stage it would appear that this is related to the mental health of the individual involved. 'Investigations will very clearly continue through the day.' New South Wales (NSW) Police Inspector Amy Scott has been praised for her bravery after she stopped the terrifying attack by shooting Cauchi dead. As the first officer on scene, Inspector Scott sprinted through the top level of the shopping complex and risked her life when she confronted the knifeman who also injured eight others. She shot the attacker - who was wearing a green rugby top - dead when he turned towards her and raised his knife. The senior police officer then performed CPR on the killer and the other victims lying on the ground as she waited for back-up to arrive. Among the victims was 38-year-old new mother Ash Good who was attacked alongside her nine-month-old baby Harriet. Just hours before the horror unfolded, Ms Good posted a photo to Instagram with her daughter in her arms. 'Only because I was walking past and happened to be wearing the same thing 9 months out vs 9 months in etc etc,' the caption read. Australian Prime Minister Anthony Albanese and the Prince and Princess of Wales have led the flood of commendations for Inspector Scott's actions. Rishi Sunak has said his 'heart goes out' to those affected by the 'truly devastating' attack in Sydney that killed six people. In a post on X, formerly Twitter, he said: 'The horrific attacks at Bondi Junction are truly devastating. 'My heart goes out to those affected by this abhorrent act of violence, and I pray for the recovery of those left injured and traumatised today. 'You are in the thoughts and prayers of the British people.'
