U.S. marshals are alerting the public of several nationwide imposter scams involving individuals claiming to be U.S. marshals, court officers or other law enforcement officials.

They are urging people to report the calls not only to their local U.S. Marshals Service office, but also to the Federal Trade Commission, which has the ability to detect patterns of fraud from the information collected and share that data with law enforcement. The U.S. marshals hope the information collected by the FTC will lead to possible arrests.

“The information people report to the FTC can help law enforcement investigate and track down the perpetrators,” said Michael McGowan, U.S. marshal for the District of Delaware.

During these calls, scammers attempt to collect a fine in lieu of arrest for failing to report for jury duty or other offenses. They then tell victims they can avoid arrest by purchasing a prepaid debit card such as a Green Dot card or gift card and read the card number over the phone to satisfy the fine.

“The U.S. marshals would never ask for a credit/debit or gift card number or banking routing numbers or ask for funds to be wired for any purpose,” McGowan said. “If the caller is urging you to provide this type of information or any other personal or financial information, hang up and report the call to the marshals and the FTC. You can even report to both agencies anonymously.”

Scammers use many tactics to sound credible. They sometimes provide information like badge numbers, names of actual law enforcement officials and federal judges and courthouse addresses. They may also spoof their phone numbers to appear on caller ID as if they are calling from the court or a government agency.

“While these callers may sound legitimate, we urge people to question their validity,” said McGowan. “The easiest way to do this is to call the clerk of the court’s office of the U.S. District Court in your area and verify the court order. If an order does not exist, someone just tried to swindle you out of your hard-earned cash.”

Victims of such scams are encouraged to report the incident to local U.S. Marshals Service office and to the FTC.
