Said they were IRS & that I was $8000.00 behind in taxes and that the cops were going to come to my house and arrest me. When I asked what address and SS# number they had for me they gave some address in the area and said they could not give out my SS#/personal information.  Then he threatened me with the cops coming to arrest me several more times before saying have a nice day and hanging up.
THIS IS A SCAM!!  Report this to the IRS on their web site www.treasury.gov
