CHENNAI: A Class XI student, studying at a private school in Chengalpet, committed suicide on Sunday after his friends bullied him for urinating in the classroom while he was asleep. Police said Bharath, 16, son of Gajendran, suffered from primary nocturnal enuresis also known as bed-wetting. He had been consulting doctors to treat the health issue. Last Wednesday, Bharath fell asleep during a free period in school and apparently urinated on the bench. One of his classmate, who saw this, allegedly told others and they teased him.Upset over this, the boy told his parents that he’d never return to school and was on leave till December 21. His father, however, convinced him and sent him to school later.On Satuday, when Bharath was home alone, he locked the doors and hanged himself from the ceiling using his mother’s saree.
