I had a similar experience. This time it was a lady with thick Chinese accent. Read my experience  below as a separate message.

I had three calls from this number and left a voice mail that was threatening. They called me back and confirmed with me my phone # and address and identified the self as the Crime Investigative Unit of the State Department. I asked if he was working with the Federal govt. he said "yes". When I asked more questions, he transferred the call to his supervisor. The supervisor identified himself as officer Jason "something". He had an authoritative and threatening tone. He said we have affidavit of three criminal charges:
1. Breaking laws and regulations,
2. Check fraud, and
3. Grand theft.
Now my wife come on line and we became more suspicious, they transferred again to another supervisor Alan "something", and started to threaten that do not talk to a state officer like that. My wife told them that we will call police. He said that he will call police department and dialed some numbers. Now someone else came online from "911" and Alan the fax number which they repeated to be a fax number from police department.
Finally we hung up and called local police department to report this incident, meanwhile these people kept calling us and we did not answer.
Local police department suggested we report this to Federal Trade Commission.

I got a similar call from 469-562-7832 while the caller ID showed 469-562-7132. I recognized it and gave him a piece of my mind.
