INDIANAPOLIS — Federal court officials are repeating their warning of a nationwide scam in which callers posing as U.S. marshals or other government officials claim victims can avoid imminent arrest for not appearing for jury duty by paying a fine.

Chief U.S. District Judge Jane E. Magnus-Stinson and U.S. Attorney Josh Minkler of the Southern District of Indiana issued the renewed warning that federal courts don’t operate in such a way and court officials, U.S. marshals or other government employees will never contact someone and demand payment or personal information by phone or email.
