PHILADELPHIA (CBS) — Federal authorities are warning the public about a jury duty phone scam.

The FBI and the U.S. Marshals Service say callers are impersonating law enforcement or court officials, telling the person on the other end of the phone that an arrest warrant has been issued for them for failing to appear for jury duty.
