ADELAIDE, Australia (AP) -- Two great white sharks attacked and killed a surfer while his friends watched in horror Thursday off a popular beach in the southern Australian city of Adelaide, authorities said.
The 18-year-old man had fallen from a surfboard being towed by a power boat when the sharks attacked off West Beach mid afternoon, South Australia state Sea Rescue Squadron spokesman Fraser Bell said.
One shark tore the victim in half and the second shark took the remains, witnesses said.
Two of the three 16-year-old boys who were in the tow boat witnessed the attack and received medical treatment for shock.
Police and state emergency services said there had been no sign of the victim or the sharks since the mid afternoon attack despite extensive searches of the coast.
Bell said the sharks, also known as white pointers, were between 5 to 6 meters meters (15-17 feet) long. They attacked about 250 meters (yards) from a crowded beach.
"He fell off the surfboard and the shark appeared and took him," Bell told reporters.
"It tore him apart ... apparently it tore him in half and the other shark came in and took the rest."
A woman on the beach who was not named told Seven Network television the shark that led the attack "caught his left arm and took him around the boat and then another shark has come in and they just took him to pieces."
The group of four friends, all from Adelaide, had been on the water for just 30 minutes before the attack.
Asked if there were any chance the victim had survived, Bell replied, "None whatsoever".
State police chief inspector David Lufty said beaches in the area would remain closed as the search continued for the killer sharks.
The tragedy is the second shark fatality in Australian waters within a week.
A 38-year-old man was killed by a shark while spearing fish on the Great Barrier Reef off northeast Australia on Saturday.
that's really scary.
