Can the Police Arrest You Without Evidence?

Being arrested can be alarming, particularly when you believe the police have no evidence against you. A common question we are asked is: can the police arrest you without evidence?

The police do not need enough evidence to charge or convict you before making an arrest. However, they cannot lawfully arrest someone based on a mere guess, personal dislike or completely unsupported assumption.

In most criminal investigations, there must be reasonable grounds to suspect that you are involved in an offence and reasonable grounds to believe that your arrest is necessary.

The Legal Test for Arrest

The principal power of arrest in England and Wales is contained in section 24 of the Police and Criminal Evidence Act 1984, commonly known as PACE.

Under section 24, a police officer may arrest a person without a warrant where the officer has reasonable grounds for suspecting that the person is committing, is about to commit or has committed an offence. The officer must also reasonably believe that arrest is necessary.

PACE Code G confirms that both parts of this test must be satisfied. There must be suspected involvement in an offence, together with reasonable grounds for believing that arrest is necessary.

What Does “Reasonable Suspicion” Mean?

Reasonable suspicion is a much lower threshold than the evidence required to charge somebody or prove guilt in court. It must nevertheless have an objective basis.

The information relied upon might include:

• A complaint from an alleged victim
• A witness account
• CCTV footage
• Text messages or social media communications
• Police intelligence
• Information supplied by another police officer
• The circumstances in which a person was found

An allegation may therefore contribute to reasonable suspicion even before the police have obtained supporting forensic, digital or independent evidence.

The information does not have to prove that the allegation is true. It may later be found to be inaccurate or unreliable. The important question is whether the arresting officer genuinely held the suspicion and whether the information known to that officer provided objectively reasonable grounds at the time.

Police officers should also consider information pointing away from the suspect. Code G specifically states that available claims of innocence and other facts capable of dispelling suspicion should be taken into account.

Why Must an Arrest Be Necessary?

Suspicion alone is not enough. The police must also be able to justify why an arrest was necessary in the particular circumstances.

An arrest may be considered necessary to:

• Establish a person’s name or address
• Protect a child or vulnerable person
• Prevent physical injury or damage to property
• Prevent the suspect from disappearing
• Allow the prompt and effective investigation of the allegation

For example, the police may argue that an arrest is required so they can secure evidence, search premises, prevent contact with witnesses or conduct an interview without avoidable delay.

The power must be used proportionately. Code G states that officers should consider whether the objective could be achieved through a less intrusive method. Where someone can be interviewed voluntarily and there is no genuine need for arrest, a voluntary police interview may be the appropriate course.

Can a Single Allegation Lead to Arrest?

Potentially, yes. The police are not required to resolve every inconsistency or complete the entire investigation before arresting a suspect.

A sufficiently detailed and credible allegation may provide reasonable grounds for suspicion. However, this does not mean that every accusation automatically justifies an arrest.

The reliability, source and context of the information matter. The police must assess the circumstances as a whole and must separately satisfy the necessity test.

Arrest Does Not Mean You Will Be Charged

An arrest is an investigative step. It is not a finding of guilt and does not necessarily mean that the police already have enough evidence to charge you.

Following an interview and further investigation, you may be:

• Released with no further action
• Released while enquiries continue
• Released on pre-charge bail
• Charged with a criminal offence

The evidential test for charging a suspect is distinct from the lower threshold required for an arrest.

What Should You Do If You Are Arrested?

You should remain calm, avoid resisting and ask why you are being arrested.

Under section 28 of PACE, you must be informed that you are under arrest and told the grounds for your arrest as soon as reasonably practicable. An arrest may be unlawful if this information is not properly provided.

You should request legal advice before answering questions about the allegation. A person detained at a police station is entitled to consult a solicitor privately under section 58 of PACE. Legal advice at the police station is free and independent of the police.

Do not assume that asking for a solicitor makes you look guilty. Early legal advice can help identify weaknesses in the allegation, preserve relevant evidence and ensure that your account is presented properly.

Can an Unlawful Arrest Be Challenged?

An arrest may be unlawful where there were no reasonable grounds for suspicion, the necessity test was not met or the required information was not provided.

Depending on the circumstances, this may give rise to a complaint, civil proceedings or another legal challenge. Code G expressly recognises that an unjustified arrest may result in a civil claim for unlawful arrest or false imprisonment.

The legality of an arrest and the merits of the underlying allegation are separate issues. Anyone considering a challenge should obtain advice based on the custody record, body-worn video footage and the information available to the arresting officer at the time.
