I have been doing many transactions to other persons through an app and receiving cashbacks on it like every 100 rupees transaction would give me 9 rupees. In which one of the transaction I got credit to my bank account of 500 rupees and that was of fraud. The cyber crime who put hold on 500 was from Karnataka I called the I O and he ask me to send email about the money stating from where I received it. As well as he is asking my Pan and Aadhar. What should I do should I give my credentials to him? Will they will start any proceeding against me?
