DC (DD) of Barrackpore commissionerate Debasish Bez, who was present at the school premises, told the agitators that principal of Christ Church Girls school Helen Sarkar had handed over a paper to him, purported to be her resignation letter.
Refusing to accept the same as the resignation letter, the agitating guardians demanded that the principal should tender it on a school pad and it should be duly stamped.
The agitating guardians laid a siege to the main gate of the school, disallowing the principal and the teachers to leave the premises since morning.
A combat force of police personnel was posted in and outside the school premises hours after a section of guardians, joined by some locals, went on the rampage, breaking furniture, equipment and damaging school property in protest against Oindrila's death.
