The use of such wanted posters dates back to the days of the American Old West when bank robbers were frequently the subject of a wanted poster. When a law enforcement agency wants to apprehend someone suspected of committing a crime, one method they use is a wanted poster. A wanted poster can include a photograph of the individual or a composite drawing of the individual, the crime for which the person is wanted, and identifying characteristics such as height, weight, scars, or tattoos. The purpose of using a wanted poster is to alert the public that law enforcement agencies are looking for the person depicted on the poster.
