Would I need to make a citizen's arrest against a US Federal agent(s) who perpetrated crimes?

I was arrested a period of time ago for "impersonating" myself. The prosectuor used all my evidence against me in a Judge trial and said that I had all my evidence, because I "wrongfully" got it (that was his 'proof'. Since then, it was was found that I was indeed who I said I was but that was after I was thrown in a federal penetentiary for a period of time with a bunch of criminals, forced to be evaluated for 'mental health' issues (of which there were none found obviously since I knew that I was who I said I was), and refused a bond and evidentiary hearing. After it was found out that I was indeed who I said I was, I called around and found out how do I have the CID members that had me placed into prison arrested for false imprisonment, obstruction of justice, and (along with the prosecutor) conspiricay to commit fraud and of cours malicious prosecution; but I was told I need to call the CID about actions that their agents did. I did this and they laughed at me. I spoke with internal affairs at CID and they said that they could not help me. How to you hold US Federal agents accountable for their own actions when crimes are committed by these. I will be filing Bivens, but how do I have these criminals arrested and held accountable for their actions?
