this is a scam

I am getting harassed by someone from this number saying I deposited a check with a bank that I am no longer affiliated with and can be arrested for check fraud.  They said they have an affidavit from that bank.  So I contacted that bank and they do not have any such complaint.  I also contacted another resource and they looked up the number and found that it is indeed a Scam and advised that I contact the Attorney General's Office.  The bank suggested I get on the Do Not Call Registry
