If you are arrested, what information must the police officer provide?

When someone is arrested in the UK, the police have a legal obligation to inform them of the reason for their arrest. This is a fundamental right, ensuring that individuals understand why they are being detained and can then seek appropriate legal advice. This principle dates back to the Magna Carta of 1215, which established the concept that no one should be imprisoned without due cause. While the Magna Carta didn't explicitly state this right as we know it today, it laid the groundwork for the legal protections that exist now. So, while a police officer will likely need to ask about your background during processing and will certainly expect you to follow instructions, the crucial initial step is to inform you of the reason you are being arrested. This allows you to understand the charges against you and begin to defend yourself.
