The big cat ventured into Jaden village, some 20 km from here, last evening and pounced upon the girl, a police spokesperson said.
The beast took away the girl into a nearby forest, from where her body parts were later recovered by police, he said.
The leopard remained untraced and joint efforts by police and wildlife department are on to locate the man-eater, he said.
This is the third such incident this week, and ninth in the past three months in the Valley.
