Deepika Negi was dragged away by the leopard when she came out of her house along with her mother at Raiwala last evening to buy something, forest department sources here said.
As her mother raised an alarm, the feline left the child after dragging her for about 50 metres and escaped into the wild.
However, the child who sustained injuries in the neck died while being taken to the hospital, they said.
As the bear attacked her she lost balance and fell off a cliff.
She died on the spot, the sources said.
