The incident occurred in Barkheda area under Govindpura Police Station when their parents had gone to the market, police said.
On Saturday night, Pandi had a fight with his brother Anees (9) over the issue of watching their favourite channels following which the younger sibling smashed the glass of a cupboard and rummaged the belongings kept in the room.
Upset over the reaction, Pandi went inside the room and hanged himself, may be due to the fear that his parents would scold him, Govindpura police station in-charge SKS Tomar told reporters.
