A 70-year-old man has been beheaded in Bihar's Darbhanga district, allegedly after he named a town square "Narendra Modi chowk", his family claims. Ramchandra Yadav, a BJP supporter, was attacked by about 40-50 men with hockey sticks and swords, who came on motorcycles, his son Tej Narayan said. "As a senior citizen, my father went to them to explain the situation but he was beheaded with a sword. When my elder brother intervened, there was a murderous assault on him," Mr Tej Narayan told the media.
