I also received this same threatening call today. Really upset me!  Warrant out for my arrest?  What?  Filing a police report also. Not sure what the scammers are getting out if this though. They didn't ask for payment or anything?!?

Yes. Just got this call and actually had a difficult time understanding what the message was. Now I know. Assumed it was a scam.

I have called FBI for this

I have received two calls from the same gentleman.  Very thick accent and difficult to understand.  I filed a complaint with the Attorney General office in the State of Ohio and California as his number is CA.  I have tried calling the number back and either get a busy signal or this number is no longer in service but he just called with that number so obviously some type of scam.  However, the fact that he keeps calling and leaving voice mails on my phone that says that police are coming to arrest me and that I need to quit ignoring him and screaming in my phone is very upsetting.  More so because I have children and if they had retrieved these voice mails it would have upset them.  Anyone else have suggestions as to whom to report this man too?  I have tried calling back as he will hear it from me but the number won't go through.  He says his name is "Ricky Johnson" calling from the IRS and that I owe him over $10,000.  WTH!

Message left on my phone machine from 415-690-1279.  Called male with a thick accent that sounded Indian claiming to be with the IRS.  He gave a reference number 494453.  Said to call immediately - time sensitive - and asked for name of attorney. I looked the phone number up in Google and found lots of people with the same stories.  I blocked this phone number.  He is dangerous in that elderly people or people who aren't savvy could fall prey to his con game.  I couldn't understand the name he gave because his accent was too thick.
