Banerjee told reporters here that Aadhaar details being leaked out was "alarming", and could be dangerous for individuals and society.
"We don't know why such acts are taking place. We already have the PAN card, voter ID card. But I believe what is taking place in the name of the Aadhaar card will be dangerous for any individual and society," she said.
Criticising the Centre, the Trinamool Congress chief said, "Some people act like Muhammad Bin Tughlaq and take sudden decisions such as dividing the state or the move of demonetisation. This information about Aadhaar card details leakage also shows such a mindset."
"Details from head to toe of every individual, talks between mother and daughter... husband and wife would be known. I have been warning (people) about this time and again," Banerjee said.
