As part of the scam, the caller identifies himself as an officer of the court. The caller tells potential victims that they have missed their jury duty and that there is a warrant for their arrest.Then, the caller tells them they can get out of it by paying a fine, which requires personal information. As soon they turn over their personal information, their identity has been stolen.The FBI has issued a nationwide alert about the scam. Warnings circulated on Wednesday via email for members of the military and their families at Camp Pendleton."What's important is we get the affected areas out in this case, Camp Pendleton and other areas in San Diego County and make people aware it is taking place so they won't be victim to fraud," said FBI special agent Darrell Foxworth.The scammers may ask for a Social Security number, date of birth or credit card number to cover the supposed fine."Your social security is the key to really ripping you off," said San Diego City Attorney Tricia Pummill.Pummill said as a rule, court officers will never ask for confidential information over the phone and will generally correspond through mail.She said the scammers' game is to scare people into giving up their personal information."That is a classic tool of the scammer's trade," said Pummill. "The con man wants to get you off your game."The jury scam has been reported in 11 other states.Authorities say the best way for citizens to protect themselves is to hang up.
