A forest official said Badal Naskar and Supriyo Naskar were catching crab when the big cat appeared and began dragging away Badal by neck.
As Supriyo tried to save Badal, the tiger pinned him to the ground but then left Supriyo and vanished with Badal in the deep forests.
Supriyo was later taken to hospital with serious injuries.
Till now Badal could not be traced by the search team comprising forest department and villagers living outside the forest buffer zone.
