Unidentified persons hacked to death the father of a BJP worker here allegedly over a tiff over naming of a square on the outskirts of the city after Prime Minister Narendra Modi.

Police, however, claimed that murder of 65-year-old Ramchandra Yadav late on Wednesday night, whose BJP activist son Kamlesh Yadav sustained injuries in the attack, was the fallout of a "personal enmity".Kamlesh Yadav, who was undergoing treatment at a hospital, told reporters "a chowk (square) at our native village of Bhadavan in Sadar police station area had been named after Narendra Modi two years ago".

SSP Satya Veer Singh said: "It was due to an old land dispute & has no connection with naming of chowk, they named their private land as Narendra Modi Chowk. Batons were used to injure the deceased's son. There is no tension in the village."
