What is one type of suspicious package threat involving no actual item?

A communicated threat represents a type of suspicious package threat that does not involve the presence of an actual item. This type of threat typically consists of warnings or messages suggesting that a package may be dangerous or contain harmful materials, yet no physical evidence of such a package exists at the time of communication.

Understanding this concept is crucial for law enforcement and emergency responders, as it helps them differentiate between real threats and hoaxes, allowing them to allocate resources effectively and ensure public safety without inciting unnecessary panic. Other options involve physical evidence or situations which involve actual items or deliveries, making them distinct from a communicated threat.
