The incident occurred after a fellow student went missing from the school the previous day.

'We have already reported to the police about the missing student. But the action of the students - they even tried to attack the headmaster and some teachers - is shocking indeed as we selflessly work towards making them disciplined and the future of our society,' a teacher of the Navodaya Vidyalaya said.

Then came other incidents of students protesting at a city college in Guwahati after a teacher pulled up a student for not dressing properly - the teacher asked a male student not to expose his chest and to button up his shirt.

'These unprecedented acts of students attacking teachers or vandalising schools and colleges is due to lack of value system in our society and this teen aggression is a result of accumulated frustration,' Sangeeta Dutta, a well known psychiatrist, said.

'The age old system of respecting teachers has gone for a big toss. The society at large is responsible for this and even the teachers would have to shoulder the responsibility as the quality and level of teachers have gone down,' Sivanath Barman, a noted academic, said.
