Harrasement to my mother

This is humbly informed you that I Nirmal Gupta R/O – CC-55B DDA Flats hari nagar, age 87 yrs is living at the above mentioned address since last 37 yrs. As I am a retired person from MCD as principal from school and have a senior citizen card. I am under constant threat from time to time by a person named Sher Singh Baghel R/O- RZ-230, Sayed Village, Paschim Vihar, Mobile number-[deleted], New Delhi. First time he visited my house on17/4/2014 and threatened me to kill my son who is living in GH-5/7, FLAT NO-651, Paschim Vihar, new Delhi if I don’t give him RS 200000/-. He also had beaten my son right in front of my eyes which was no bearable for me as a mother. I gave him the cheque of RS-200000/- on 5/5/ 2014 number 34209 and he forced me to write a self cheque as he never wanted to mention his name. However I asked to write a letter where he mentioned that he would never touch my son again. The torture never stopped at this point as I was again approached by the same person on 29/7/2017 bringing my son and once again started beating him with his two more associates demanding 150000/-. My son was kept under captivity for overnight before bringing him to me at a place unknown to him. I once again fell to their demands as a lonely lady and issued him a cheque for RS-150000/- from my SBI Account Hari Nagar branch no-[deleted] but this time I wrote his name which he cashed from SBI Meera Bagh branch the same day. I and my son have been living under constant threat from this person as he is blackmailing us from time to time and threatened me to cut my son into pieces after throwing them somewhere near Sonipat(HARYANA). Even after giving 350000/- in total till date. I was regularly being asked by respected beat officer Shri. Bhupinder Rana about my well being but because of fear I was not able to report the matter but finally I gave a call to him and requested to help me out which he did. I would request you to kindly get my money back and save me from this torture and let me live my last days in peace. As a mother I can’t afford to see suffering of my kids. Hence you are requested to kindly save me from the clutches of this blackmailer and help me out to live peacefully.
