Panic gripped a village in West Bengal's Nadia district after locals said they heard "nocturnal howls" of a creature, which is yet to be spotted.
Residents of Fulia Chatktala in Shantipur police station area said they have been hearing such cries after sunset for about a week.
They said the forest department was also informed but officials who were keeping a close watch on the area for two days found nothing.
However, officials were tight-lipped about the matter.
"We didn't care for the first few days, but as it continued, people were panic-stricken. They are keeping doors and windows of their houses shut and also not allowing children to go out alone," said Amal Basak, a villager.
He said bones and skins of some puppies have been found in the village.
