I took loan from my friend few years back without any legal documents and paid interest for some time. Later I requested him that I can't pay interest any further and started to repay the actual amount in monthly instalments. I have proof nor the payments made by me. There is very less amount pending as of now. Suddenly he started behaving violently and took my signature on empty stamp paper forcefully. He came along with a police person to take my sign. I don't know what he will do with that. What should I do now? What are my risks? Is the document valid? Kindly help. Its urgent.
