Hari Chauhan, a sharecropper, was set on fire late last night at Sumka village in the Tharthari police station area of Nalanda district, SHO Sunil Kumar Rajak said.
The son of the farmer, Sanoj Kumar Chauhan, lodged an FIR in this regard, the SHO said adding that the barbaric incident was being investigated.
The assailants tied Chauhan's hands and legs and set his thatched hut on fire. They also destroyed the paddy crop he had in his store.
The farmer had taken 20 bighas of land on lease from Shiv Kumar Prasad for paddy cultivation.
However, the police said, being physically challenged, the landlord could not himself execute the murder and probably got it done by other persons.
