threat letter
Written anonymous warning
A threat letter is a written communication—typically anonymous—that threatens harm, violence, or consequences unless demands are met.
The term appears frequently in law enforcement and security contexts: The CEO received a threat letter demanding the company change its policies.
Such letters may threaten individuals, organizations, or public figures, and are often criminal offenses regardless of whether the sender intends to act.
