Cnp Solution — online fraud, blackmailing, mental torture

I got a call from a company for captcha work job. I send them a voter id copy and email for the work. After 15 days, i got a call from an unknown number that i need to pay them rs. 8000 penalty for not completing the work. They said that for not paying penalty file case against my father. They also threatened me with legal harassment. Now i want to know, can the frauds do anything with my aadhaar card copy which can make me suffer in future?
Please solve my problem.
Thank you
