PATNA, March 28 -- Three children-all siblings aged 5-10 years-were allegedly hacked go death by their uncle at Khuthatan village under the Haspura police station area in Bihar's Aurangabad district over a family dispute on Friday, police said.

The deceased were identified as Anish (10), Ayush (7) and Anushka (5) while the accused was identified as Amant Pal (18) who suppressed the children's screams by playing loud music during the ghastly incident. SDPO (Daudnagar) Ashok Kumar Das said the accused had locked the room from inside before the incident. "We had to break through the ventilator to get in," he said. Police said the bodies of the three were lying in a pool of blood inside the room. The matter came to light when their mother Anita Kumari returned home after worshipping in a temple. When she tried to open the door, it wouldn't open. Suspecting a foul play she started crying. People from nearby areas reached the spot, broke open the door and were shocked to see the scene.
