According to police, the incident took place last night when the accused, Harichand, was at his in-laws' house.
His 11-year-old brother-in-law was watching television at a high volume. "Harichand was constantly nagging about the high volume. He soon lost his patience and allegedly attacked the boy with a stone. He crushed his face with the stone and locked the door from outside and fled the spot," a police officer said.
"When they entered the house, they found their son lying in a pool of blood. He was immediately rushed to a nearby hospital where he was declared dead on arrival," the police officer said.
A case of murder has been registered at Nihal Vihar police station and efforts are being made to trace the accused.
