He is employed from the local area, and was speaking to a number of young people that he knew through family and friends, and another group of young people took offence to that conversation that the 36-year-old male was having with those young people, and as a result of that … that 36-year-old male is now [allegedly] murdered."Superintendent Darrin Batchelor says it appears the altercation stems from a chance meeting. (ABC News)Before being stabbed, the man had been planning to help some of his young family friends at the scene get home safely."He was doing a good deed. He went to an ATM to withdraw money so that those [young] people could get home safely," Superintendent Batchelor said.Police are expected to carry out further arrests and charges after seizing multiple mobile phone videos and CCTV footage of the incident.Family left distraughtThe deceased was described as a family man with children, with his loved ones "obviously distraught" by his death."A family has lost a father, a son, a brother," Superintendent Batchelor said.Though forensic testing is still to occur, investigators believe they recovered the weapon used in the incident, a knife, from a drain outside a Cabramatta unit block.Over the weekend, a nearby worker recounted hearing screaming on Friday night and saw children running from the scene.Another local called emergency services at the time when he saw the man on the ground."Everyone was helping [him] … it scared a lot of people," he said.NSW Premier Chris Minns told 702 ABC Sydney on Monday that while he would not comment on the specific case, he was worried about the rise in younger cohorts of people committing violence crimes."That is a particularly heinous and morally objectionable," he said."We need to make sure that we've got policies in place to meet that threat where it's most acute."
