That has forced some big cats to turn to human-dominated landscapes for survival, which leads to livestock, and sometimes people being killed.The operation was led by Bihar police, who surrounded a sugarcane field near the village of Sitaltola Baluwa to kill the three-year-old tiger known as T-104.Kumar Gupta, chief wildlife warden for the region, told the Times of India the tiger had been identified as "dangerous to human lives".Attempts to tranquilise the animal were unsuccessful and the tiger showed a "complete lack of fear" when surrounded by teams, Mr Gupta added.Bihar's wildlife warden said there was no information available to suggest the killings of people had been carried out by another tiger."
