Term used by U.S. and Canadian law enforcement

"Person of interest" is a term used by law enforcement in the United States, Canada, and other countries when identifying someone possibly involved in a criminal investigation who has not been arrested or formally accused of a crime. It has no legal meaning, but refers to someone in whom the police and/or domestic intelligence services are "interested", either because the person is cooperating with the investigation, may have information that would assist the investigation, or possesses certain characteristics that merit further attention.
