Annulment of marriage

Sir, my marriage was registered on 16th september,2016 under special marriage act of 1954. the next day of the registration i came to know that whatever he had told me about his profession and personal status as well and educational background all were false. it was my mistake that me and my family believed on his words and did not verify. now when i am asking him for divorce , he is continuously threatening me to made some of my pics viral which we had taken during our relations.he is also pressing me to continue the relation as well sending immense messages to my sister and family members to prove his innocence. althroughout he sent me so many demoralizing messages to put me under severe mental pressure. when i blocked him he is now disturbing my family by means of sending messgaes. since he had done everything with preplanning he got pics and videos of me whereas i have nothing as such since me and my falimy belived him and his sweet words. he also has created facebook account and posting his and mine pictures there without my permission.i have already informed at lalbazar but they are avoiding by saying that am his legal wife and here he does not require my permission. please suggest how to get rid of this miscreant
