Last week, I received several phone calls within a 24-hour period of time from this number, the caller claimed to be from the U.S. Treasury Department; demanding that I pay monies to avoid a warrant being issued for my arrest. Told the caller to [***] and hung up. He called back several times leaving nasty messages that he will have me arrested and worse if I didn't cooperate; very aggressive and persistent.  Called my local Sheriff's department and had the incident logged and learned this scam is nation-wide and unfortunately, many people have fallen for it.
