In the
USA an
amber alert is a notification to the general public by commercial radio, broadcast television, or electronic traffic-condition signs, regarding a confirmed
abduction (usually of a child). The decision to declare an amber alert is made by the law-enforcement organization investigating the abduction. Public information in an amber alert usually consists of the name and description of the abductee, the description of the suspected abductor, and the description and license plate number of the suspect vehicle.
