A woman has plunged into crocodile-infested waters after her bungee rope snapped.

Erin Langworthy had jumped from the Victoria Falls bridge above the Zambezi River, when the cord snapped in two.

She told Australia's Channel 9 News "it went black straight away and I felt liked I had been slapped all over".

She said she had to swim with her feet tied together to the Zimbabwe side of the water, and had to free the cord when it got caught on rocks.
