SYDNEY, Australia (AP) -- Lifeguards at a beach post north of Sydney couldn't believe their eyes when a man walked in with a small shark attached to his leg.

Luke Tresoglavic swam 300 meters (1,000 feet) to shore, walked to his car and drove to the local surf club with the 60 centimeter (23 inches) shark biting his leg and refusing to let go.

"I just realized I had to swim in like that, hanging on to it," Tresoglavic told Australian Broadcasting Corp. radio on Wednesday.

Tresoglavic, 22, was snorkeling on a reef off Caves Beach near Newcastle on Tuesday when a wobbegong, or carpet shark, attacked his leg.
