Scammers are calling Idaho residents and threatening them with arrest unless they pay a "fine" to settle out of court. The phony calls have been reported in the Boise, Pocatello and Twin Falls areas.

So, what happens is a caller claims to be a deputy U.S. marshal and tells the person answering the phone that they have a pending arrest warrant, which can be waived if the person pays a fine. Some of those targeted by the scam say the caller suggested they buy a prepaid Visa or Mastercard, and provide the number on the back of the card to the caller.

It's only natural to have a fear of breaking the law if you get a call like this, but officials say a valid arrest warrant would be served in person.

Never give out any personal information over the phone to anyone who calls you, and notify police immediately if you receive a call like this!
