The around the 60-year-old victim, Phandi Sardar, is undergoing treatment in a hospital.
"He is now stable. Our personnel visited him at the hospital and recorded his statement. His son has lodged a police complaint today (Wednesday). A detailed investigation is on," said an officer of the Parui police station.
"six people have been detained for interrogation," he said.
The officer said Sardar used to perform some pujas or rituals, due to which the villagers thought he was involved in dark practices.
"This apparently pushed them to this inhuman act. We are looking into all possible angles," he said.
