An "APB," or All Points Bulletin, is a broadcast issued by law enforcement agencies to alert officers about a suspect or a person of interest. It provides essential details such as the individual's description, last known location, and any relevant vehicle information. The goal is to quickly disseminate information to help locate or apprehend the individual. APBs are often used in urgent situations, such as when a crime has just occurred or when a suspect is considered dangerous. They can be communicated through various channels, including radio, email, and police databases, ensuring that all officers are informed and can respond effectively.
