Boy, 12, dies from injuries after Sydney shark attack

Key Highlights

• He was always full of life and that's how we'll remember him," his family, who were originally from Argentina, added. Nico's friends were praised for their bravery after jumping into the water to help him after he was attacked last Sunday afternoon. However he suffered serious leg injuries and was taken to Sydney Children's Hospital in a critical condition.
• He was placed in an induced coma after undergoing surgery. An online fundraiser set up for Nico's family has raised $240,000 (£121,308). There has been a spate of reported shark attacks along Australia's east coast in the past week, three of them in Sydney.
• On Monday, a surfer on Sydney's northern beaches escaped a lurking shark without physical injury, while hours later a 27-year-old man suffered "life-changing" injuries in a shark attack at a nearby beach.
• One day later, a man on the Mid North Coast of New South Wales was pulled from the water after surviving a shark bite. The man, 39, sustained a chest wound and was taken to hospital.
• The attacks followed several days of heavy rain, which experts say created a "perfect storm" of conditions for bull sharks who prefer murky water.
