The girl was lifted from her courtyard by the big cat late last night and dragged into the bushes about 500 km away from her home, Tehri DFO Kokoroso said.
The leopard ran away as people gathered at the spot after hearing the loud cries of the girl.
But by the time villagers reached the spot the girl was dead, the Divisional Forest Officer (DFO) added.
Villagers complained that the forest department had been informed about a leopard being sighted frequently in the area but it didn't act promptly.
