The crime occured on Saturday in Uttam Nagar in west Delhi but was reported to police on Tuesday after the intervention of a Child Welfare Committee and the 13-year-old boy's family filed a complaint against five classmates.
"The boy refused to go to school on Tuesday. When his parents asked him the reason, he disclosed the incident. His family then complained to the Child Welfare Committee and Uttam Nagar police," a senior police officer said.
"The boy, a student of Class 8, was ragged by his classmates a year ago on knife-point. A teacher had seen accused students carrying a knife on Saturday after school hours and scolded them for being on campus at that late hour," the officer said.
Three of the five accused students have been suspended by school authorities. The boy's counselling is on.
