United States Marshals protect the federal courts, track down dangerous fugitives, and transport thousands of prisoners. They don’t make calls and threaten to arrest people or fine them for missing jury duty. But scammers posing as Marshals have been making calls like that and tricking people into sending money. The imposters use spoofed phone numbers that look official, and steal the names and badge numbers of legitimate law enforcement officials. They warn people they might be arrested — unless they buy a prepaid debit, iTunes or gift card and pay the fine immediately. If you buy a card and tell a scammer the card’s code, the scammer takes the card’s value; your money is gone. If a “U.S. Marshal” calls you with a jury duty warning, hang up. It’s a scam.
