Citizen's arrest

What is citizen's arrest?

In the United Kingdom, a citizen's arrest refers to the legal power granted to any private individual, not acting as a sworn law enforcement officer, to apprehend someone they reasonably believe is committing or has committed an indictable offence. This provision, primarily detailed under Section 24A of the Police and Criminal Evidence Act 1984 (PACE), empowers ordinary citizens to intervene in specific criminal circumstances. This power is not absolute and comes with strict conditions, including the requirement for reasonable grounds for suspicion and the use of only necessary and proportionate force. The primary purpose is to prevent the continuation of an offence, to prevent injury or loss, or to allow for the apprehension of an offender until the police can take over.

Navigating the legal boundaries of intervention

While the power of citizen's arrest exists for all individuals, its application carries significant responsibilities and potential legal ramifications. Individuals must ensure they have reasonable grounds for suspicion and use only necessary and proportionate force to prevent escape or summon police. Misjudgements can lead to accusations of assault, false imprisonment, or other legal challenges. Therefore, it is generally advisable for private citizens to prioritise their own safety and act as witnesses, reporting incidents to the police rather than attempting an arrest themselves. Intervention should only occur when absolutely necessary to prevent immediate harm or loss, and with a clear understanding of the legal boundaries involved.

Professional responsibilities for security personnel

For security professionals, understanding the nuances of citizen's arrest is paramount, as they often find themselves in situations requiring immediate action. While they possess no greater legal powers than any other citizen in this regard, their training equips them to assess risks, apply reasonable force, and manage detainees until police arrive. This professional context demands a thorough knowledge of PACE and associated guidelines. Effective training for security personnel focuses on de-escalation techniques, proper documentation, and the critical importance of handing over suspects to law enforcement promptly. This ensures that any intervention is legally sound, protects the rights of all parties, and contributes positively to public safety without overstepping legal authority.
