PATNA, Oct. 25 -- A 20-year-old youth was arrested after he allegedly beheaded his 18-month-old brother with a sharp-edged weapon at a Durga temple in Bihar's rural Patna on Saturday, police said. The accused identified as Ajit Kumar alias Bala had been arrested and the investigation was underway, the police said. An FSL team inspected the spot and collected evidences. The police have also recovered the weapon used for the murder. The police said that villagers found the head of the toddler at the temple at Jitan Chhapra village under Ranitalab police station area of Paliganj subdivision in Patna. "We received information around 11.50 am that the accused, identified as Ajit, killed his one-and-a-half-year-old brother with a dabiya (cleaver) inside a temple premises in Jitan Chhapra village," Paliganj Sub-Divisional Police Officer (SDPO) Pankaj Kumar Sharma said, adding that the motive of the murder was not yet clear. Bikram Circle Inspector Chandrika Prasad said Ajit beheaded his younger brother with the murder weapon inside the temple, but the speculation of 'bali' or sacrificial offering to the deity remains unsubstantiated as of now. The family members said that accused Ajit had taken the toddler to the temple at around 10am at the pretext of feeding him prasad and that hours later, the news of the child's beheading broke. The family said that they didn't know why the elder brother turned to such butchery....
