Harihar Choudhary, a resident of Bhatwalia village in Gopalganj district, was beaten to death by his three nieces while he was ploughing the field Friday, police officer Anand Kumar Pandey said.

"Choudhary's nieces told him not to plough. But when he refused, they attacked him with bamboo sticks and beat him to death," he said.

A case has been lodged against Choudhary's nieces on the basis of his wife's statement. The three accused are absconding.
