Jamshedpur, Aug. 29 -- Two persons were arrested on charges of hacking a couple and their son to death in Kenjra Taroburu tollah under Tonto police station in Jharkhand's West Singhbhum, police said on Friday. "In preliminary probe, the case appears to be a fallout of a dispute over land. On August 26, Ragmaiya Doraiburu had filed a plaint at Tonto PS alleging that three of his family members had gone missing. He also alleged that some unknown criminals had killed them and hidden the bodies,' Raphael Murmu, Jagannathpur SDPO, said on Friday. Murmu said West Singhbhum SP Amit Renu formed an SIT under the Jagannathpur SDPO, to probe the incident. "A raiding team under Jhinkpani inspector Premchandra Bhagat and Tonto PS OC Dhananj Singh arrested two persons -- 19-yr-old Bonj Doraiburu and 20-yr-old Muchia Doraiburu from the same village. Both confessed to have killed 40-yr-old Rajin Doraiburu, his 38-yr-old wife Jano Doraiburu and their 12-yr-old son Kande Doraiburu with axe and dumped the bodies in the jungle," said Murmu....
