Just got the call in Los Angeles, same threatening message. I am sure people get scared and fall for the scam.

Scam posing as us treasury. Kyra leavitt badge 110471.  And Anthony Cooper
 Both of Indian or Pakistani

same message, irs, actually did leave a call back, which I did not record, the irs is after me and they will lock me etc....there was one on tv news last night, when they were exposting the calls for scams, they did call back, got the same voice-and they said he could be the one going to prison-he replied ina gleeful voice"It's a Praaaaaank!"....obviously, do not believe it, the IRS will not contact you by phone, at least, not initial contact. I kind of doubt any real office or officer would ever use a call to make contact.

Why can't this Dude be tracked with knowing his phone number?  I received the same threats while I was on vacation.

I received 2 phone calls today.  2nd time a message was left stating same info as everyone else.  I did return the call and a man with heavy accent answered stating verbatim all the info as everyone else regarding 2010 taxes etc. I ended up hanging up.
