The United States Federal Bureau of Investigation (FBI) maintains a public list of the people it regards as the ten most wanted fugitives. The list itself has no particular ranking. It is commonly posted in public places, making it effective in expediting the capture of those listed. Listed fugitives have been known to turn themselves in upon becoming aware of their listing. 476 fugitives have been listed, and 446 captured, 145 of them due to public assistance.
