The leopard attacked a shopkeeper Nandaballabh Tiwari, injuring him, even as police and forest department staff were on guard.
One of the forest department staff fired a tranquilizer shot, and the animal vanished. As police and forest officials went out in search of the leopard, he was sighted again, and another tranquilizer was shot.
The leopard collapsed in a heap. He was rushed to a vet doctor who referred him to Pantnagar, but the animal died on the way, said Avneesh Kumar, a forest dept official.
