I approached Global for tracing of one particular subject person relating to fraudulent documents submitted to a goverment office by him, that effected a claim I had under UK law. Global stated the level of tracing and costing prior to me accepting their services. Global was transparent, no hidden fee's or costs and the timeline given, in my case there was a small time overrun only because of the level of detail, due diligence and further detail with their investigations in uncovering a fraud. I was overwhelmed with the report result with supporting evidence that was well worth the wait, you can't rush quality! There was so much compelling detail, that provided me with the evidence that I need to overturn such a fraudulent document. I would highly recommend Global Investigations Ltd to anybody in a similar situation. Global are most professional in all aspects of dealing with my case. They kept me updated prior to investigation completion with excellent communication. A most sincere thank you to Global's Team!

I was initially hesitant since my case required an investigation all the way in Africa. However, Jack was incredibly patient and walked me through all of my questions with total professionalism. The results gave me the exact clarity and confirmation I had been seeking for years. Thank you to Jack and his team for their excellent support. Global Investigations Ltd is a completely legitimate, professional, and trustworthy service.

Our first time using a tracing agent, Michelle was brilliant and guided us through the process whilst answering our many questions. We thought we were in a hopeless position with our case but we're thrilled with a positive result in the end.

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.
