Expectations

Missing Persons — Authorised Professional Practice

All topics

Summary

This College of Policing Authorised Professional Practice (APP) page details the expectations of police when responding to missing persons incidents. Officers are tasked with safeguarding individuals reported missing and must thoroughly assess risks to inform resource allocation. Legal expectations stem from the European Convention on Human Rights, compelling officers to act reasonably to protect the rights of individuals at risk. The response begins with an initial risk assessment, which must account for any vulnerability or unique circumstances of the missing person. Governance and strategic oversight are essential for effective investigation, highlighting the importance of proper leadership and accountability within police forces. A cyclical investigation cycle is essential for addressing underlying causes for a person going missing, and officers must differentiate between varying categories of missing person cases, ensuring appropriate actions are taken based on the level of risk involved.
