Fears that a crocodile had set up home in a river have been allayed after zoologists said it was more likely to be a giant turtle. The crocodile theory began when boat trippers on the River Lea in east London, saw a Canada Goose apparently pulled under water at speed.
But experts say an alligator snapping turtle, which can grow to about two metres, is a more likely culprit. The creature may have been a pet which was released into the wild.
