Got a call from this number as well stating  there the US treasury and ignoring this call will lead to legal action ...

I just got the same threatening call. They left a voice mail. I hope unsuspecting people read these posts and don't fall for this scam!

Received call from someone who identified themselves as James Casten regarding a criminal offense and said if I failed to call back it could lead to arrest for a Treasury violation and an appearance before a magistrate judge or a grand jury.  What a load of BS.  I trust this has been reported to the real authorities, although I have doubts they will act in a timely manner.

I answered it was a recording that threatened action

These people need to be caught, extremely threatening call.
