Altogether 90 of the 247 students of Class XI of the school had failed in the annual examination conducted by the West Bengal Council of Higher Secondary Education.
The school authorities could not do anything in this regard due to norms of the Council, he said.

The meeting between students and the authorities including the secretary began at 9 am but failed to resolve the issue till 10.30 when the school was closed for the day, Pattanaik said.
When students of all the others classes left, these 90 students locked the outside gate keeping inside 52 persons - all the teaching and non-teaching staff and Pattanaik.
Sources in the local police station said they had been informed by the school about the incident but were hesitating to take any action as a large number of school students were involved.
