A 20-year-old body boarder was killed when a giant shark estimated at up to five metres long bit off his leg in a Cape Town bay, in South Africa's second deadly mauling this year.
David Lillienfeld's brother Gustav tried to pull him to safety when the shark struck while the siblings were bodyboarding, reported Eyewitness News website.
"The deceased man sustained complete amputation of his right leg, below the hip, while body boarding with his brother and friends," said National Sea Rescue Institute spokesman Craig Lambinon.
"There are no other bite marks or lacerations on the deceased man's body - only the complete amputation of the right leg and the leg has not been recovered."
Witnesses reported a single shark, thought to be a Great White and measuring four to five metres, attacked the man. They said up to six sharks were spotted after the incident at a popular surfing and body boarding site in False Bay.
