Stalking and Harassment Investigations UK

Stalking and harassment are serious and often deeply distressing experiences that can affect every aspect of a person’s life — from their sense of safety to their mental wellbeing. Whether it happens online, in person, or both, this behaviour is never acceptable and should never be ignored or dismissed.

Global Investigations is dedicated to support and provide guidance for anyone who may be experiencing stalking or harassment or who wants to better understand these issues, explanations of what stalking and harassment are, how to recognise the signs, and what steps can be taken to protect yourself and seek help.

If you are interested in reclaiming your safety, our stalking and harassment investigation services may be your solution.

What is Stalking?

Stalking is a pattern of repeated, unwanted behaviour directed at a person that causes them to feel distressed, scared, or unsafe. It is not usually a one-off incident, but a series of actions over time that create fear or anxiety. Stalking can take many forms, including:

What makes stalking particularly serious is the impact it has on the victim.

Even actions that might seem minor on their own can become frightening when they are repeated or part of a pattern of behaviour.

Stalking simplified is if someone’s behaviour is making you feel uncomfortable, unsafe, or harassed and it keeps happening, it may be stalking — and it should be taken seriously.

Understanding the Profile and Behaviour of Stalkers

Stalking can be carried out by a wide range of people and there is no single “type” of person who becomes a stalker. However, certain patterns are often seen.

People Known to the Victim

In many cases, stalking is carried out by someone the victim already knows. This can include:
In these situations, stalking may begin after a relationship or connection has ended, especially if one person struggles to accept the change.

Strangers

Some stalkers have no prior relationship with the person they target. This might involve:
This type of stalking is less common but can still be very serious.

Online (Cyberstalkers)

Some stalkers have no prior relationship with the person they target. This might involve:
Stalkers can be any gender, age or background. There is no single motive, some may seek control, revenge, attention or a relationship. The behaviour is about patterns and persistence, not just single actions.

Take Back Control With Professional Stalking Investigations

We work with clients to uncover evidence, often providing the ‘smoking gun’ required for police action or a Stalking Protection Order. We can help you in turning the table on your stalker by the range of services we provide including:

Court Checks – Criminality

This service will help you understand an individuals’ legal history. We undertake extensive Court checks both locally and nationwide to determine any past or pending Court appearances.

Background Checks

This is one of our most popular services as fraudulent activity and identity theft are becoming much more common. The need to know whom you are dealing with or about to engage in personal or professional relationships with is paramount. Our comprehensive reports will provide peace of mind.

Surveillance

We can perform three types of surveillance depending on the circumstances – static surveillance (monitoring outside a property), mobile surveillance (following an individual from place to place) and field surveillance (our operatives use specialised equipment such as thermal imagery for surveillance in rural areas).

Relationship Checks

We perform checks to determine if the individual has been previously married or has any children from a previous relationship.

Digital Profile Search

This is a deep web search that locates digital footprints connected to names, telephone numbers, emails etc. This is a useful tool in uncovering a person's digital online presence.

Risk Management

Our risk management services help identify threats, reduce exposure, and improve personal safety both online and offline.

Our Specialist Due Diligence Investigation Services

We offer several due diligence services. Please see below:

TSCM & “Bug” Sweeps: Searching homes, offices, and vehicles for hidden audio/video recording devices or physical GPS trackers, such as AirTags.

Digital Forensic Analysis: Examining smartphones and laptops for unauthorised “stalkerware” or tracking apps.

OSINT & Anonymous Tracing: Using Open-Source Intelligence (OSINT) to unmask anonymous online harassers, fake profiles and those behind “doxxing” campaigns.

Covert Surveillance: Discreetly following a suspect to document a “pattern of behaviour” (e.g., repeatedly showing up at the victim’s work or home) with time-stamped video evidence.

Counter-Surveillance: Deploying a second investigator to watch the client’s surroundings and catch the stalker in the act of following.

Evidence Dossier Preparation: Compiling all physical and digital evidence into a professional report that meets the “criminal standard of proof” required by the Police or CPS.

Background Profiling: Conducting deep-dive background checks on suspects to uncover past histories of domestic abuse or harassment.
