Money lent to a person and she putting case against me

I am a doctor , settling down after marriage in another state. In course of time being befriended by a "good" client, had given to her 20 lakh rupees with a promise that either she will repay or she will send her land to me, she had given certified land documents. (2007) she was paying me a little amount of interest for 5 months and suddenly all of sudden she absconded. After a period of 1-2 years she came with one more lady to my house and the woman started mediating about this matter and promised in a rude way that she will try to get my money back if I listen to what she tells. After 25 days she came to me at night and took signatures in a stamp pamper that is written in another language and told she will get my money at the earliest. After this they kept on torturing me every time and told that I will be put behind bars if I ask money. One day they came eith6 rowdies and demanded 6 lakhs in lieu of these papers. I never gave and afterwards I tried the help of police but in vain. They also took money from me making false promises. Now in 2015 suddenly the crime Branch police called me and told that they have recovered a paper from a lady after doing raids and want to investigate. They investigated and started insulting me and telling that I am greedy and some bad words. Because of this pain and insult I couldn't continue my practice ,I discontinued it and left India in course of time to start a new life abroad after getting police clearance. Now in 2018 I get a information that Chargesheet is filed against the lady and I am the third accused and they have stated that I am absconding. What should I do? Please contact and help me. I am tired of this system.
