I received this message today:
Hi, this message intended to contact you. My name is Steve Martin and I'm calling regarding enforcement actions executed by US treasury intending your serious attention. Ignoring this will be an intentional second attempt to avoid initial appearance before a magistrate judge on a grand jury for a Federal criminal offense. My phone number is 713-481-5118 again 713-481-5118 again . I advise you to cooperate with us and help us to help you.
You may happily delete the message, but do tell all your friends about this well known scam by foreign criminals. Before a 'Grand Jury'? Now that's funny!
