Got two voice mails from this number - IRS has a criminal case against you if you do not call back this second (that was a giveaway!!) we will have to proceed with your arrest.
Woman called (automated) said to listen to this call to avoid criminal proceedings based on a warrant from Washington D.C about and IRS problem. If I don't call them back they are going to issue an arrest warrant. She did not identify the organization or who the call was for. So I hung up. Callers number is 1-347-390-0870
