What is 'missing'?
The National Police Chiefs' Council's definition for missing: 'Anyone whose whereabouts cannot be established and where the circumstances are out of character or the context suggests the person may be subject of crime or at risk of harm to themselves or another'.
However, there is difficulty in providing a singular definition for missing. This largely stems from the huge variety of potential reasons behind a person going missing, and the different ways an incident may be understood by different parties. Adults, unless they are within the criminal justice system or detained under various sections of the Mental Health Act, have a legal right to go missing.
