I got the same call at work, when I called back a David Cooper(no english) answered saying he was the supervisor. He preceded to tell me that there were 2 federal warrants for my arrest. At that time I informed him that I work for a police dept and no there were no arrest warrants out for me. He then got irate and started swearing at me. I then filed a complaint with the FTC federal trade commission. I called the number back again and informed them never to call me at work or on my cell phone again that I had filed the complaint. He hung up. I have called back and now only get a busy signal. This is a scam- fraud- BTW so all of you know there is NO FEDERAL LAW DEPT-
