On being informed, police rushed to Amritibattoli village in English Bazar police station area and rescued Ajeda Bibi. She was later admitted to Malda Medical College and Hospital.
The woman had in 2009 lodged a police complaint in her capacity as incharge of a child education centre against some youths after construction material was found stolen from the school compound.
Following this, Bibi was threatened. A kangaroo court set up at the insistence of the accused youths barred her from entering the village. Since then, she had been residing at another place, police said.
The woman came back to Amritibattoli but refused to pay the fine. Villagers on the direction of the kangaroo court then tied her to a tree, police said.
