When Pradyuman Thakur - a Class 2 child - was killed in September in his school toilet in a Gurgaon school, it sparked a national debate on safety in schools. But just two months later, the CBI today made the extraordinary claim that he was killed by a senior student of the same school. But perhaps the most shocking revelation by the CBI is that the the Class XI student did it to delay examinations and a parent-teacher meeting. There have been many instances of stress-induced suicides by school students, but was this is a stress-induced homicide? Is the Pradyuman case a flashpoint for our investigation agencies as well as our schools? We debate on The Buck Stops Here.
