An American tourist's holiday in the Bahamas turned into a nightmare when she lost her leg after being savagely attacked by a shark.
Heidi Ernst, a retired physical therapist from Marshalltown, Iowa, was attacked just a month after completing her 500th scuba dive.
The 73-year-old was at a dive site known as "shark junction" near Taino Beach in Grand Bahama. Heidi was on a ladder climbing up into the boat when the shark clamped down on her left calf.
