United States

For serious crimes, the police typically handcuff the suspect (even if he/she is not being violent) and bring him/her to a police station or a jail where he/she will be incarcerated pending a judicial bail determination or an arraignment. In other instances, the police may issue a notice to appear, specifying where and when a suspect is to appear for his/her arraignment.

England

In English law, whether a person has been arrested does not depend on the legal authority of the person enforcing the arrest, rather it depends upon whether he has been deprived of his liberty to go where he pleases. Whether an arrest is lawful depends on whether the police officer or civilian exercising the arrest is acting within the scope of her or his powers.

Upon arrest a person must ordinarily be taken to a police station as soon as is practicable, but may be released on bail.

United Kingdom

Any person (civilians) has the following powers to effect arrest without warrant:

Code G to the Police and Criminal Evidence Act 1984 deals with powers of arrest under section 24. The wide power under section 24 of the Police and Criminal Evidence Act 1984 may only be used if it is necessary to:

• ascertain the person's name or address;
• to prevent the person
• causing physical injury to himself or any other person,
• suffering physical injury,
• causing loss of or damage to property,
• committing an offence against public decency, or
• causing an unlawful obstruction to the highway;
• to protect a child or other vulnerable person from the person;
• to allow prompt and effective investigation; or
• to prevent the disappearance of the person.

Police officers also have powers to arrest under warrant. Civilians have restricted powers of arrest without warrant in relation to very serious offences and to prevent a breach of the peace.

United States

The reading of the Miranda warning or similar "caution" to an arrestee advising him or her of rights is not legally required upon arrest. A legal caution is required only when a person has been taken into custody and is interrogated. Legal cautions are mandated in the US, most Commonwealth and other common law jurisdictions, and countries where the right to legal counsel, the right to silence, and the right against self-incrimination have been clearly established.

United Kingdom

In the United Kingdom a person must be told that he is under arrest, and "told in simple, non-technical language that he could understand, the essential legal and factual grounds for his arrest". A person must be 'cautioned' when being arrested unless this is impractical due to the behaviour of the arrestee i.e. violence or drunkenness. The caution required in England and Wales states,

You do not have to say anything, but it may harm your defence if you do not mention when questioned anything which you later rely on in court. Anything you do say may be given in evidence.
