In 1966, authorities in Jessore, East Pakistan (now Bangladesh) were seraching for a "monster" that had terrorized the small village for days on end. The police said the beast came out at night to attack villagers before "vanishing". It had already killed a baby girl, attacked a cab driver and a woman, and slaughtered several cows.
I could uncover no clear description of the creature. Jessore lies between Nepal / Bhutan and the Bay of Bengal, about 3 hours northeast of Kolkata (Calcutta). This puts it squarely between the realms of the "Mande Burung", an ape-man known to the people of Bangladesh.
