Rcv'd call from this number from a Mike Rogers, VERY heavy foreign accent & a badge number for this "agent", from the IRS (asked for meaning of acronym was told Internal Revue Service) looking for my mother.  When I stated she was unavailable, he demanded to know who I was, which got the blood boiling ~ you called me!!!  We called back later & Mr. Rogers stated it was in reference to Tax Evasion. I asked for a Supervisor/Manager & was told there wasn't one to which I threw out a BS card & called him on it & he hung up. Called the number back & got a "Supervisory Agent" Keith Anderson, who said he was with the Investigation Office. Asked for a case number & was told they were taking legal action since I was being unreasonable. I demanded a case number, which I was given, I asked for a toll free number which is 1-800-829-1040 & I asked for their office address (denied). Asked for more specifics & when I asked for a letter to be mailed to me regarding this "matter", he said he would notify my local sheriff & have me arrested before the night was over & then he hung up on me. No answer when I attempted to call the number back. Going to post this wherever I can & get hold of the Chicago IRS office in the morning along with an email.

Total scam run out of India.  First off, the IRS does not file lawsuits.  If there is a need for court action, the IRS makes a request to the DOJ which makes the final decision whether or  not to go to court-- usually to enforce a collection action of some kind or another.    See:   http://www.irs.gov/irm/part5/irm_05-017-004.html
But this only happens   after a long period of administrative negotiations with the taxpayer.   Before any court case would happen, the taxpayer would be well aware of it.   IRS is never going to cold-call you and tell you that a case is being filed against you  out of the clear blue sky.  
IRS has absolutely no authority over local police.  Local police and law enforcement are NEVER involved in tax disputes.     If law enforcement presence is needed , US marshal are available.  
Secondly, over 90 percent of all tax disputes are settled administratively during an appeals process.  
This is just a scam where somebody cold-calls, pretends to be IRS and  tries to scare you into paying money to somebody by Green dot money pak which is untraceable.
Ignore the call and do not return it.  Block the number.  Never return these kinds of calls.  They are looking for vulnerable people they can brow-beat into paying them something.  If they sense vulnerability they will hammer that person with more calls.
