A young boy who was bitten by a shark in Sydney Harbour last week has died in hospital. Twelve-year-old Nico Antic had been jumping off a rock ledge with friends on 18 January when he was attacked by what authorities suspected was a bull shark. We are heartbroken to share that our son, Nico has passed away, his parents Lorena and Juan said in a statement. The incident was one of four reported shark attacks along the New South Wales coast over two days. Nico was a happy, friendly, and sporty young boy with the most kind and generous spirit. He was always full of life and that's how we'll remember him, his family, who were originally from Argentina, added. In a display of bravery, Nico's friends jumped into the water to assist him after the attack. Despite their efforts, he sustained serious leg injuries and was transported to Sydney Children's Hospital in critical condition, where he underwent surgery and was placed in an induced coma. An online fundraiser for Nico's family has raised $240,000 (£121,308). Alongside this tragedy, a spate of shark attacks has been reported on Australia's east coast over the last week, with three incidents occurring in Sydney alone. Following several days of heavy rainfall, experts suggest that the conditions may have drawn sharks closer to shore, prompting safety measures including beach closures across Sydney.
