An All Points Bulletin (APB) is a
broadcast issued from one
law enforcement agency to another. It typically contains information about a wanted
suspect who is to be arrested or a
person of interest for whom law enforcement officers are to look. They are usually dangerous or missing persons. As used by police, the term dates to at least
1960. An all-points bulletin can also be known as a BOLO, which stands for "be on the lookout". It is sometimes called a "lookout" or "BOL" for short.
