It's a scam that goes by such names as MoreStar Consultancy, LLC; Litigation Consulting Service, LLC; Claims & Warrants; and North American Asset Investigation Bureau, LLC (NAAIB). For details, read consumer credit advocate Bud Hibbs' report on these scammers: http://budhibbs.com/debtcollectorpages/NAAIB.htm
One thing it remember is that anytime someone calls you demanding money to prevent your arrest or criminal charges, it is ALWAYS a scam. No debt collector (let alone criminals posing as debt collectors) have the authority to have anyone arrested for anything. (And it's illegal to them to threaten such a thing.) These type of crooks also routinely impersonate FBI agents, police and other law enforcement officials, which, obviously, is illegal as well. (Besides, law enforcement officers aren't in the business of debt collection, and debt is a civil, not a criminal, matter.)
The bottom line is, these are criminals trying to steal your money. Ignore their illegal threats and report their attempts to extort money from you to all these federal and state law enforcement agencies:
1) The U.S. Secret Service is responsible for protecting the country's financial infrastructure and payment systems from international and domestic threats. Call or write your local Secret Service field office to alert them to the details of this attempted extortion. The addresses and phone numbers for the local Secret Service field offices are listed at http://www.secretservice.gov/field_offices.shtml or in your phone book.
2) Alert the FBI at https://tips.fbi.gov Be sure to tell the FBI that you are being targeted by extortionists over the phone and give them all the details.
3) Maryland Attorney General http://www.oag.state.md.us/Consumer/complaint.htm (Litigation Consulting claims to be in Maryland)
4) Your state's attorney general, the contact information for whom is at www.naag.org
5) File a complaint with your local police. Most police departments will take a report over the phone. Be sure to tell them that you're being targeted by an extortionist and give them all the details.
6) File a complaint with the Federal Trade Commission https://www.ftccomplaintassistant.gov/FTC_Wizard.aspx?Lang=en
If these criminals call back, tell them that they aren't getting any money from you and that you've reported their scam to federal and state law enforcement. They will react with the usual moronic, false threats. If possible, try to save any voice messages they leave and, if legal in your state, record their calls if you speak with them. (Inexpensive phone recorders are available at Radio Shack-type stores.)
