The body of a 52-year-old man, who was accused of engaging in "unnatural physical activities with a cow", was found hanging from a tree in West Bengal's South 24 Parganas district, police said.
Local residents spotted the body of Gautam Patra hanging from a tree outside his house in Ghoramara-Hathkhola village on Thursday, they said.
A preliminary investigation suggested that the deceased was "accused of doing unnatural physical activities with a cow in the village last week, over which he was being subjected to public ridicule. A handwritten note has been recovered from his pocket", a senior police officer said.
A kangaroo court was held on Wednesday on his alleged activities with the cow, but no decision was taken, the officer said.
The body was sent for postmortem, the officer said, adding that further investigation is under way.
