Well John in Texas, the same thing happened to me. When they called back and I told them the local authorities had been told, the person hung up the phone.

Someone purporting to be from IRS, arrest warrant out in my name. haha Threatning foreign sounding man. Said if I didn't pay what I owed in taxes I would have to pay 35,000 in court fees and would still lose. Would take house, car, credit cards and I would lose my job. Gave arrest warrant number, case number, etc. Hung up when questioned.
