How to Get Unlawful Arrest Compensation

Being arrested by the police is a serious and often distressing experience. For many people, it can feel frightening, humiliating and disruptive to both personal and professional life. When that arrest turns out to be unlawful, the impact can be even greater. If the police did not have proper legal grounds to arrest you, or failed to follow the correct procedures, you may be entitled to unlawful arrest compensation.

Many people assume the police cannot be challenged, or that compensation is only available if no further action was taken. This is not the case. The law provides important safeguards to prevent misuse of police powers, and where those safeguards are breached, individuals have the right to seek redress.

This guide explains what an unlawful arrest is, how compensation works, and the steps you can take to bring a claim against the police.

What is an unlawful arrest?

An unlawful arrest occurs when the police arrest someone without meeting the legal requirements set out in law. In England and Wales, police arrest powers are governed primarily by the Police and Criminal Evidence Act 1984 (PACE).

For an arrest to be lawful, two key conditions must be met:

The officer must have reasonable grounds to suspect that you have committed, are committing, or are about to commit a criminal offence
The officer must reasonably believe that arrest is necessary, for example to prevent harm, protect evidence, or allow an effective investigation

If either of these conditions is missing, the arrest may be unlawful, regardless of how serious the alleged offence might be.

Common examples of unlawful arrest

Unlawful arrests can happen in many different circumstances, including everyday encounters with the police. Common examples include:

Arrest without reasonable suspicion
Arrest where voluntary attendance or further enquiries would have been sufficient
Failure to explain the reason for arrest clearly
Arrest based on incorrect, outdated, or unreliable information
Arrest motivated by discrimination or improper purpose
Continued detention after the justification for arrest no longer exists

Even short periods of detention can amount to an unlawful arrest if the legal threshold was not met. In such cases, you may be entitled to unlawful arrest compensation, even if you were released without charge.

What rights do you have when you are arrested?

When you are arrested, the police must respect a range of legal and human rights designed to protect you from unfair treatment. These include the right to:

Be told that you are under arrest
Be informed of the grounds for arrest as soon as practicable
Access free legal advice
Have someone informed of your arrest
Be treated with dignity and respect
Receive appropriate medical care if needed

If these rights are ignored or delayed, it may strengthen a claim for unlawful arrest and false imprisonment.

What is unlawful arrest compensation?

Unlawful arrest compensation is a civil remedy available to individuals who have been wrongly deprived of their liberty by the police. It is not about avoiding responsibility for wrongdoing; it is about ensuring that police powers are exercised lawfully and proportionately.

A successful claim may include compensation for:

Loss of liberty, even for short periods of detention
Distress, anxiety, and humiliation caused by the arrest
Physical injuries sustained during the arrest
Financial losses, such as lost income or expenses

Claims for unlawful arrest are often brought alongside claims for false imprisonment, assault, or breach of human rights, depending on how the arrest was carried out.

How much compensation can you receive for unlawful arrest?

There is no fixed amount for unlawful arrest compensation. Each case is assessed on its own facts. Factors that can affect the value of a claim include:

The length of time you were detained
Whether handcuffs or force were used
Conditions of detention in custody
Any physical or psychological injury
The seriousness of the police misconduct
Whether the arrest took place in public

Compensation awards can reach sums in the thousands of pounds in serious cases involving prolonged detention or significant harm. For more details on this aspect, please read our prepared blog on the subject.

How to get unlawful arrest compensation

If you believe you were arrested unlawfully, taking early and informed steps can make a significant difference to your claim.

1. Write down what happened

As soon as possible, record details such as:

Date, time, and location of the arrest
What the officers said and did
Names or badge numbers of officers
Names of any witnesses

2. Preserve evidence

This may include:

Custody records and release paperwork
Medical records or photographs of injuries
CCTV or body-worn camera footage
Phone records or messages showing the impact of the arrest

3. Seek specialist legal advice

Claims for unlawful arrest are complex and robustly defended by police forces. A solicitor experienced in actions against the police can assess whether your arrest was lawful and advise on the best route forward.

Do I need to make a police complaint first?

You do not need to make a police complaint before pursuing unlawful arrest compensation, although some people choose to do so.

A complaint may result in:

An explanation or apology
Internal disciplinary action

However, a complaint alone will not lead to compensation. Compensation can only be obtained through a civil claim against the police.

What if I was charged or convicted after my arrest?

Being charged or even convicted does not automatically prevent you from claiming unlawful arrest compensation. The key question is whether the arrest was lawful at the time it occurred.

If the police lacked reasonable suspicion or necessity when arresting you, the arrest may still be unlawful, even if later proceedings took place.

Is there a time limit for unlawful arrest claims?

Yes. Time limits apply, and they can vary depending on the legal basis of your claim:

Most unlawful arrest and false imprisonment claims must be brought within six years
Claims under the Human Rights Act must usually be brought within one year

Because these limits can overlap and differ, early legal advice is essential to avoid missing a deadline.
