Collusion by Police

I'm from Bangalore. I filed an FIR for loan recovery against which the police was to file the chargesheet against the individual. The police from the beginning was very lax in their approach and after PCR filed the FIR. Instead of taking any action, they waited for 3 weeks to allow the accused to get their (husband & wife) anticipatory bail. Then they kept delaying the investigation citing other more important cases. When they were aware that I was out of town, they sent a letter to my residence stating that I should report to the police station within 3 days to commence with further action on my FIR. This is about more that 6 months that the FIR was filed. My lawyers informed them of my situation as I was dealing with a medical issue in the family. Once I returned and visited the police station, the IO says that the charge sheet has been filed and is with the Deputy Director of Prosecution for Scrutiny and then the matter will reach the court which will give me a date after a year and then I can take up this matter with the courts. He was very rude and visibly annoyed since he was pulled up by his seniors. However, what surprised me was when his junior (an ASI) then called me in and told me that he would like to retake my statement since they needed to file the chargesheet. This contradicted the IO's statement. I did give my statement which was typed out in Kannada language. I told the ASI that I do not understand what was written and I need to show this to someone or my advocate before I sign. He got extremely upset on this and threw a tantrum saying that I don't trust them and that they are doing it for my good. Also he mentioned that if I sign or don't sign, it does not matter, they will send it to court anyway. I tried reaching out to may advocate at around 10pm but he too was not available. Caught in the situation and putting my trust in the law, I signed. While preparing my statement, the ASI asked me how I have so much of current information about the accused and I showed him his social media accounts. At the same time, since it was mentioned in the FIR that the accused is conducting business under company names that do not have any legal existence, he made a note of this. SURPRISINGLY, on the very next day the accused blocked me from their social media accounts and also put some certificate trying to indicate that they are affiliated with some company that is associated with the ministry of higher education. Thats my REASON FOR DOUBT
