"We have arrested all the four accused and booked them for murder. A special investigation team headed by Additional Superintendent of Police Sanjay Shau will probe the incident," Deputy Inspector General of police (Bhopal) Dharmendra Choudhary said.
The accused were identified as Teeran Yadav, Prakash Yadav, Sanju Yadav and Balvir Yadav. Mr Jatav, who belonged to the Dalit community, protested when the four men tried to encroach on a piece of land leased by him, following which the accused allegedly set him on fire after pouring petrol on him, the DIG said.
The family members of the victim took him to a nearby hospital, where he was declared brought dead. Chief Minister Shivraj Singh Chouhan condemned the incident and said the culprits would not be spared.
"When will the government stop atrocities against Dalits?" he asked. Mr Nath also constituted a committee of Congress leaders Kailash Mishra and Asif Zaki, who have been asked to visit the farmer's family and submit a report.
