The heavly accented fellow at the other end said "I am from the Internal Revenue Service Police"

I would have laughed and hung up the phone.

WARNING!!!!! DO NOT GIVE THESE CALLERS ANY PERSONAL INFORMATION!!! Look up your information at IRS.gov or call the IRS office!!!!
I received the Same call, a heavy East Indian accent I could not understand a word... Stated that I should call back because there is something wrong on my taxes? Hmmmm really. So I called back to track the call and their answering machine  states that the IRS office is closed right now (sounds like someone home machine) still a heavy accent. I've dealt with the irs before and you normally would go through a computerized phone service with several selections before ever getting to a real person (as with most government offices) and the irs would also have contacted you via mail with any issues with your taxes. They would never seek legal action as a first course of action. This is blatant fraud and I suggest anyone getting this message file a formal complaint with the irs. They are trying to take advantage of people while they are filing taxes and scam your tax return.
