Same message I found from (954) 674-6472 from this guy pretending to be DEA Special Agent Michael Thomas and requesting a call back pertaining a "current criminal investigation".  I have informed the real FBI and DEA about this scam.

They call from this number saying that I have a court order, because I did not apper, this person said that I was buying medicine without prescription, and this person said that the police was on their way to take me.
I said okay I'm waiting for them to come, I don't have any problem in receiving them.

I got the same phone call from this number 323-515-4049 and was saying sheriff is coming over to serve you just stay where you are :-)
