The people who have been called by this scammer are being told that they failed to report for jury duty.
They are told all they need to do to stay out of trouble is pay a fine.
The caller threatens that the person can be arrested, fined and face jail time if they don't provide personal and credit card information.
Marshals say the caller has also asked several victims to use money wire services to satisfy the fine for failing to report for jury duty.
The US Marshals Service and US District Court want to remind people that they do not ask for sensitive information to be provided over the phone and their representatives would not request personal or credit card information.
They also do not use money wire services to send money for any purpose.
If you get a call from anyone saying you missed jury duty and asking for personal information, or if you believe you have been a victim of this crime, you're asked to contact the us marshals service.
