A wanted poster is a poster put up to let the public know of a criminal whom authorities wish to apprehend. They will generally include either a picture of the criminal himself when a photograph is available, or of a facial composite image produced by a police artist. The poster will usually include a description of the wantee and the crime(s) with which he is charged. Wanted posters are usually produced by a police or other public government body for display in a public place, such as on a physical bulletin board or in the lobby of a post office, but in ages past wanted posters have also been produced by vigilante groups, railway security, private agencies such as Pinkerton, or by express companies that have sustained a robbery.
Wanted posters for particularly notorious fugitives frequently offer a reward or bounty for the capture of the person, or for a person who can provide information leading to such capture.
Wanted posters, when produced by non law enforcement sources can be a type of harassment. In the wake of the Duke University lacrosse case, wanted posters were distributed with the photos of 40 members of the lacrosse team on them. Some anti-abortion activists have also used wanted posters as a form of harassment against abortion providers.
