You are likely thinking of the Bengal tiger, not a "bangel" tiger.
Bengal tigers are native to the Indian subcontinent:
India: Largest population, in various protected forests.
Bangladesh: Found in the Sundarbans mangrove forest.
Nepal: Smaller population in the Terai region.
Bhutan: Very small population in southern foothills.
Bengal tigers are endangered due to habitat loss, poaching, and human-wildlife conflict.
