Jury duty scams are on the rise again, so watch out for these fraudulent calls. Typically the caller says it's the Gwinnett Sheriff's Office calling to tell the victims that they didn't show up for jury duty and that they now owe a fine of as much as $900, which can be paid over the phone with a prepaid debit card. Gwinnett County's law enforcement agencies do not call people to demand money.

Every year, thousands of potential jurors in Gwinnett are selected randomly by computer from a database of registered voters and licensed drivers and summoned by mail. The summons explains the one-day-or-one-trial system and gives instructions on when and where to report for duty. If you don't show up, they contact you again - also by mail.

If you've been scammed, report it to the Gwinnett County Sheriff's Office Investigative Services Division at 770.619.6655.
