A sunny beach day in Brazil became a nightmare as a young boy was mauled by a shark so viciously that horrified bystanders had to drag him to shore, bloody footage of the incident shows. The youngster suffered severe injuries to the left side of his body, including an amputated leg, during the attack at Piedade Beach in Jaboatao dos Guararapes around 1:40 p.m. local time Sunday. Video shot at the beach shows a group of men pulling the boy’s motionless body to the shoreline and appearing to call for help from others nearby. Local media identified the boy as Joao Lucas Castor Nemezio Sales, who was at the beach with his uncle, Aldemir Jose, and two other children.
