Caller left message saying he was from Illegal Affais at the US Dept of the Treasury. Said law enforcement was about to arrest me and that I should call back immediately. Wished me to have a "good life" if I didn't call back. When I called back and said I worked for a federal agency and asked for identification and other information, caller hung up and now I only get a busy signal when I call back. Obviously a fraudulet call, but disturbing.
