tourists detain a suspect without any police being present outside of Buckingham Palace. *

There is a related newspaper article about this incident on Daily Mail.

Neither case sees a police officer in the vicinity.

There have been problems in the past about one person keeping another ‘restrained.

The Tower Hamlets case remarks that the suspect has been arrested by police but the Buckingham Palace case has no comments as to the further development.

See also advice from Met Police about this issue.

This is the answer ‘Ask the Police’ gives to the question 508: “Can you tell me about Citizen arrest”?

This area of law is very complex and the following is only basic guidance. The law states that:

• Any person can arrest a person who is in the act of committing an indictable offence or
• Anyone whom he reasonably suspects to be committing such an offence, if
  • it is not reasonably practicable for a constable to make the arrest instead and
  • there are reasonable grounds for believing that the arrest is necessary, for one of the following reasons:

To prevent the person in question:

• causing physical injury to himself or any other person;
• suffering physical injury;
• causing loss of or damage to property; or
• making off before a constable can assume responsibility for him.

There a few points to note about the above paragraph.

1. What is an indictable offence?

An indictable offence is an offence that can be tried at Crown Court. Below are examples of indictable offences which are the most likely to be encountered by members of the public:

• theft
• burglary
• criminal damage.

2. How do I know if I can make a citizens arrest?

You can make an arrest if the suspect is actually committing the offence or if you reasonably suspect them of committing it, or when the offence has been committed and you reasonably suspect them of having committed it.

There is no specific wording to use when making a citizens arrest. However you must inform the person you are arresting as soon as possible what you are doing, why you are doing it and what offence you believe the person has committed.

There are other considerations to make when making an arrest:

• in the first instance, where practicable, you should contact the police and only intervene if absolutely necessary.
• do not make a citizens arrest if you feel that you would be putting yourself or any other person in danger, ring 999.
• reasonable force – see link in related information for details on reasonable force.
• potential for civil litigation – the courts are sympathetic to public spirited citizens and the exercise of their powers and rights, however, if you get it wrong you could be sued for unlawful arrest and/or false imprisonment.
