What Is Stalking?

Stalking is a serious criminal offence in England and Wales involving repeated, unwanted and persistent behaviour directed at another person that causes them fear, alarm or distress. Although there is no single statutory definition in the way there is for some offences, stalking is criminalised under specific sections of the Protection from Harassment Act 1997 as amended, and supported by police guidance and statutory protection orders.

This guide explains what stalking is under law, the behaviours that can amount to the offence, how cases are prosecuted, potential penalties, civil protection measures, and practical questions for victims and those responding to allegations.

Introduction to Stalking Law

Before legislative change in 2012, stalking in England and Wales was prosecuted under general harassment provisions of the Protection from Harassment Act 1997, but there was no dedicated stalking offence. Lawmakers therefore amended that Act to create specific stalking offences in recognition of the distinct and serious nature of persistent stalking behaviour.

Stalking is treated as a form of harassment that involves repetition and fixation and is distinguished from one‑off incidents by the pattern and impact of the conduct.

Statutory Framework and Legal Basis

Protection from Harassment Act 1997

The core legal basis for stalking offences in England and Wales remains the Protection from Harassment Act 1997, which originally tackled harassment generally but was later expanded:

• Section 2A creates the offence of stalking;
• Section 4A creates the more serious offence of stalking involving fear of violence or serious alarm or distress.

The Protection from Harassment Act also provides civil remedies, including injunctions to prevent further stalking and compensation for victims, but this article focuses primarily on criminal law.

What Constitutes Stalking

Statutory Elements

To commit the offence of stalking under Section 2A, a person must:

1. Pursue a course of conduct that amounts to harassment of another person, and
2. The pattern of conduct must amount to stalking.

Under statutory guidance, conduct amounts to stalking if it:

• Amounts to harassment of the victim, and
• Involves acts or omissions associated with stalking, and
• The person whose conduct is in question knows or ought to know that it amounts to harassment of the other person.

The law does not list every possible behaviour capable of amounting to stalking, but it provides examples of stalking‑associated acts, including:

• Following a person;
• Contacting or attempting to contact them by any means;
• Publishing material relating to or purporting to originate from the victim;
• Monitoring internet use, email or other communications;
• Loitering in public or private places where the victim may be;
• Interfering with property in the victim's possession; and
• Watching or spying on the victim.

These behaviours illustrate the persistent, intrusive and unwanted nature of conduct that may constitute stalking; none are an exhaustive list and not all need be present for prosecution.

More Serious Offence: Fear of Violence or Serious Alarm or Distress

Under Section 4A, a court must be satisfied that the course of conduct caused the victim to:

• Fear that violence will be used against them on at least two occasions, or
• Suffer serious alarm or distress with a substantial adverse effect on their everyday activities.

This represents a heightened level of harm and tends to attract more serious penalties.

Penalties and Criminal Consequences

The seriousness of stalking offences varies by level:

• The basic stalking offence (Section 2A) may be tried summarily with penalties such as imprisonment up to six months or a fine on summary conviction, or both.
• The more serious stalking offence involving fear of violence or substantial distress (Section 4A) is triable either way and on conviction can attract imprisonment for up to ten years and/or a fine, reflecting the gravity of harm caused.

Penalties may be enhanced if offences are aggravated by factors such as racial or religious hostility.

Protective Orders and Civil Measures

Stalking Protection Orders

The Stalking Protection Act 2019 complements criminal law by providing for Stalking Protection Orders (SPOs), which police and courts can seek to prevent further stalking behaviour before or after criminal proceedings. Such orders may include prohibitions on contacting the victim, being in particular areas, or using digital communication. Breach of a protection order can itself lead to criminal sanctions.

Injunctions and Compensation

The Protection from Harassment Act also allows victims to bring civil claims for injunctions to stop stalking conduct and for damages for anxiety and financial loss resulting from stalking, even where a criminal prosecution does not proceed. Civil claims operate on the balance of probabilities, a lower standard of proof than criminal cases.

Reporting, Prosecution and Legal Process

Reporting to Police

Stalking is a crime that can be reported to police. Evidence may include witness statements, digital communications, CCTV recordings, travel records, call logs and other documentation of persistent conduct. Police assess whether there is sufficient evidence and whether prosecution is in the public interest under the Crown Prosecution Service (CPS) charging standards.

Criminal Proceedings

Cases proceed through the Magistrates' Court for less serious offences or may be sent to the Crown Court for serious charges, especially when fear of violence or serious distress is alleged. Defendants have the right to legal representation and to challenge evidence and legal elements at trial.

Time Limits

Some stalking and harassment offences are subject to a six‑month time limit for prosecution from the date of the last conduct, although more serious offences may not be strictly limited in the same way; early legal advice is important to navigate procedural requirements.

Rights and Support for Victims

Victims of stalking have rights within the criminal justice system, including access to specialist support such as Independent Stalking Advocacy Caseworkers (ISACs) and assistance from victim support services. Police and prosecutors are encouraged to consider protective measures early in investigations.

Victims are also entitled to be informed about progress of cases and to give evidence sensitively, with safeguards available to manage trauma and risk.

Practical Examples of Stalking

Stalking behaviour can range from overt physical acts to digital intrusion and monitoring:

• Repeatedly following a person in public;
• Persistent unwanted messages, emails or calls;
• Monitoring someone's social media or internet use without consent;
• Regularly loitering near a person's home or workplace;
• Publishing content about a person intended to harass or unsettle them;
• Interfering with property or sending unwanted items repeatedly.

Individually, these actions may not constitute a crime, but when seen as part of an ongoing pattern they can amount to stalking.

Common Questions About Stalking

Is stalking only committed by strangers?
No. Stalking can be perpetrated by any individual whose behaviour is persistent and unwanted, including former partners, acquaintances or strangers.

What is the difference between stalking and harassment?
Stalking is a form of harassment involving specific behaviours showing fixation and repeat conduct; harassing behaviour may be less obsessive and not qualify as stalking unless it meets the statutory criteria.

Can online behaviour alone be stalking?
Yes. Persistent online contact, monitoring or publishing material relating to a victim can constitute stalking if it forms part of a pattern causing alarm or distress.

Key Takeaways

Stalking in England and Wales is a criminal offence grounded in the Protection from Harassment Act 1997 and its amendments, including Section 2A and Section 4A, supported by police and prosecution guidance. It involves persistent, unwanted conduct that amounts to harassment and demonstrates fixation or obsession, such as following, contacting, monitoring or spying on a person. The law recognises both standard and aggravated stalking with corresponding penalties up to ten years' imprisonment. Civil remedies and protective orders complement criminal law to enhance victim safety and provide avenues for compensation and restraint.
