Forestry officials told the Times that several dozen people formed a group with the intent of killing the tiger.
H. Rajamohan, the tiger reserve’s field director, told the Times that someone had speared the tiger, and as it lay on its back, thrashing in the grass, villagers repeatedly hit it with sticks and machetes.
Rajamohan said the tiger crawled into the jungle, where the mob continued to beat it.
That is where the tiger died several hours later, Rajamohan said.
CNN reports that as a result of the incident, four people were arrested and 31 received an initial complaint from the local forest department.
