I just got this same call at my place of work stating he works for a Lawyers office and that I have a warrent out for my arrest and that they will be picking me up either my place of employment or my home tomorrow. His name was Mr Walker from 712-283-4255

Do not give these people any information it is all a scam and they try to scare people into giving information or money - if there was a real legal issue they wouldn't call you they would just be serving you - I have sent my information on these people to the local authorities and on to the FBI - they have called my cell phone and work and they need to be stopped - the more information people give them the more they stay around to scare people - so sad.

this message for Monica no last name. It was important that I call or my attorney. He spoke with a Philipino accent don't recall the name. I have received calls from this number about 2 weeks ago stating I would arrested at my job or home. I was recently involved in money scam and that is when these calls started. The general involved in the scam was Alex Edwards representing the company FastCash Loans in Los Angeles. His number is 323-739-7180.

Typical Indian scammer.

This is the correct Firm name at that address:

Corbett, Anderson, Corbett, Vellinga & Irvin, L.L.P.
423 6th Street, Suite 400
P.O. Box 3527
Sioux City, IA 51102
Phone: 712-277-1261
Fax: 712-277-6631

This is a legitimate law firm, so far as I can see.

The scammers are using that address and a slightly different name for scam purposes.  

You're not going to get any legal case up against the scammers because they are located in India and are pretty much bullet-proof against American law enforcement.
