Locanto — Personal information misused/ threatened

A person with contact number [protected] is blackmailing me on watsapp, he copied my photos from Facebook and is misusing my information, he is asking me for money and is threatening me that he ll spoil my career. He has sent me a screenshot wherein he has created an account on Locanto as escort dealer using my mobile number and photo without consent. I have already filed an FIR also. Such activities should be nibbed to the bud and such monsters should be put behind the bars.
