Roane County Sheriff's Office is warning the public of a local scam that contacts people saying they missed jury duty.
Authorities say that the scammers leave messages informing people they missed jury duty and there is a warrant for their arrest.
The scammers go on to say that the only way to fix the problem is to go to Kroger, load a green card with $500 and then call them with the card information.
If you receive a call like this, you can contact the sheriff's office at (865) 717-4700.
