A tigress that strayed into Deulbari village of West Bengal's South 24 Parganas district on the outskirts of the Sunderban Tiger Reserve (STR), was pelted with stones and beaten by local residents as it lay in a sedated state in a pond after being darted by forest personnel with tranquillisers and forced down a palm tree atop which it had taken shelter on Monday morning. The frightened animal was rescued from the pond and taken by forest staff for examination by veterinarians. It was to be released into the forests, N. Singhal, Field Director, STR, said.
