SCAM person by the name of Brian.  Beware! From Federal Dept. of Investigation.

The same thing happened scam calling from Federal Dept, of Investigation 202-506-9199 and to call back.  Very Creepy with a heavy accent.  His name was Brian and asked to call back on this urgent matter. TOTAL SCAM! BEWARE!

I had the same experience. Did you check your phone bill to see if you got extra charges as one of those 800 numbers? I called my phone company but they can only tell me in my next billing cycle.

Fraud caller who leaves a threatening msg. Don't even bother calling back...

Just received a phone call from the same Indian guy but he told me that there had been a formal complaint filed against me and that I needed to call Brian Johnson back. The only information he had was my name, address and phone number. I called my son and he conferenced in the Indian guy, I asked for Brian Johnson and when he found out my son was on the line he hung up.  Total scam report it if it happens to you, I am.

Just called me this morning with a very threatening message.  Said that I better not disregard this call, that it is a 'security' matter.  He had an accent from India and stated he was from 'Safety Investigation Office' .  The caller ID stated Washington DC.  I reported it with my attorney general.  Very creepy.
