Accusing you of being a criminal when you are not one is hostile and if your bosses do not put a stop to it they should be ashamed. If they let a hostile workplace fester then you can sue them for it if you are fired. The co-worker, if he is causing you loss of reputation or costs you your job, can be sued for defamation if he has called you a criminal.
Far too many variables exist in the short post you wrote for any further observation by me. Many attorneys have information posted here on Avvo.

An indictment is issued by a grand jury, grand jury proceedings are secret and their deliberations carefully guarded. It would be impossible to guess what this person is talking about or what information they really have. If you have any reason to believe they are telling the truth, you should contact a good criminal defense lawyer in your area as soon as possible. This response is not legal advice and is offered for informational purposes only.
An indictment means that you have been formally charged with a crime by the Prosecution.

As my colleague indicated, to be federally indicted would mean that a federal prosecutor has presented a proposed indictment to a federal grand jury and that the grand jury has determined that probable cause exists for the indictment to be returned. It sounds like you should consult with an attorney in your area about all the issues which you have raised here. Good luck!
