If I had no idea about a fraud they claim it was me how do I get out of it?

Sounds very fishy to me.  If the "investigator" is from a law enforcement agency, ask what law enforcement agency he is with, then look them up and call them directly to see if there is an investigation against you.  If you were really subject to arrest and law enforcement knew how to get in touch with you, they'd most likely just come and arrest you.  Let's assume, for the sake of argument, that you did pass a bad check. Passing a bad check may be a class 1 misdemeanor or a class 6 felony. A.R.S. 13-1807.  Generally, the former has a one year statute of limitations and the latter has a seven year statute of limitations. A.R.S. 13-107.  Unless the times were tolled for some reason, you are probably not subject to prosecution for passing a bad check.  If this is a debt collection agency, they are very likely violating the Fair Debt Collection Practices Act by misrepresenting the character of the debt as enforceable or saying that you can be prosecuted (among other violations). See https://www.ftc.gov/enforcement/rules/rulemaking-regulatory-reform-proceedings/fair-debt-collection-practices-act-text I suspect this is some kind of scam trying to scare you into sending them a check or giving them your credit card number.  Consider reporting the caller and their phone number to the Arizona Attorney General's office and/or the police.
