Groupe Hyperion on TF1’s news: when a private detective in Montpellier presents a real investigation

An investigation in Montpellier under TF1’s cameras

The report follows Jeremy Fontanille on an assignment commissioned by a company in the Montpellier area. The context: an employer suspects that an employee on sick leave is engaging in an activity incompatible with the health condition they declared. A situation that is unfortunately common and raises legitimate questions for business leaders.

The objective of the investigation is clear: to establish objective facts, document them precisely, and produce evidence that can be used legally. No judgement, no subjective interpretation—only factual observations that will enable the employer and their legal counsel to make the appropriate decisions.

TF1’s teams filmed several phases of this investigation: reconnaissance, discreet surveillance, photographic findings, and drafting the final report. A rare immersion that reveals the behind-the-scenes reality of a profession that is often little known to the general public.

A profession above all about patience

It is the sentence that perhaps best sums up this profession. As Jeremy Fontanille points out in the report, being a private detective means accepting to spend long hours watching, waiting, observing without anything happening… until the moment when the decisive finding can be made.

This patience is not passive. It comes with constant vigilance, a continual ability to adapt to circumstances, and absolute discretion. Every movement, every decision must be weighed so as not to compromise the assignment while remaining within the strict limits of legality.

Because that is indeed the central point: a licensed private detective works within a very precise legal, moral and ethical framework. Any evidence obtained outside this framework would be inadmissible in court and could even backfire on the employer who used it.

Fraudulent sick leave: a growing issue for businesses

If TF1 chose to devote more than three minutes to this topic, it is because the issue of fraudulent sick leave affects many French companies. The economic losses linked to these abuses are considerable, not to mention the impact on work organisation and the social climate.

Faced with this situation, employers often feel powerless. How can they verify an employee’s claims without infringing on their privacy? How can they collect evidence admissible before the labour courts? That is precisely where the private detective comes in.

At Groupe Hyperion, we regularly conduct this type of investigation in Montpellier and throughout the Occitanie region. Our mission is to document the situation factually: is the employee on sick leave carrying out parallel paid work? Are they engaging in leisure activities incompatible with their declared health condition? These findings, made in strict respect of privacy and only in public places, constitute evidence admissible in court.

A profession strictly regulated by law

The TF1 report usefully reiterates a fundamental point: the private detective profession is regulated in France. You do not become a private investigator overnight.
To practise this activity legally, several conditions must be met:
State-recognised training, provided by institutions such as IFAR, ESARP or certain law faculties. This training covers the legal, technical and ethical aspects of the profession.

Administrative authorisation issued by the CNAPS (National Council for Private Security Activities), after verification of the candidate’s criminal record and professional skills. This authorisation may be withdrawn in the event of misconduct.
Compliance with the Internal Security Code, which precisely defines the scope of intervention of private investigation agents. Article L621-1 states that our activity consists of “collecting information or intelligence intended for third parties, with a view to defending their interests”.
This strict regulation is a guarantee for our clients: it ensures that the evidence collected will be admissible before the courts and that the methods used respect everyone’s fundamental rights.

Significant media impact for Groupe Hyperion

Since this report aired on TF1, Groupe Hyperion has received many calls from companies in Montpellier, Toulouse, Perpignan and other cities in the region. Many were discovering that it is possible to call on a private detective to resolve complex internal issues.

This media coverage helps demystify our profession. It shows that the private detective is not a fictional character, but a legal intelligence professional who intervenes in real situations, with tools and methods that are perfectly regulated.

For businesses, it is also an opportunity to understand that they have legal means to defend themselves against abuses: fraudulent sick leave, unfair competition, internal theft, breaches of non-compete clauses… All situations in which a private investigation can provide decisive evidence.

For individuals, the report reminds viewers that our services are not limited to business matters. We also intervene in personal and family contexts: fidelity checks, searches for missing persons, inheritance disputes…

Why this TF1 feature is important for our profession

Beyond the recognition for Groupe Hyperion, this report represents progress for the profession as a whole. It helps make known the legitimate role that private detectives play in the French judicial system.

Too often, our profession is associated with questionable practices or intrusive methods. The reality is quite different: we are auxiliaries of justice, in the same way as bailiffs or court experts. Our work consists of establishing facts, collecting evidence using legal methods, and enabling our clients to assert their rights before the courts.

This national broadcast also helps raise public awareness of recent developments in case law concerning evidence obtained by private detectives. As we explain in our article on evidence in labour law, investigation reports are now increasingly accepted by labour courts, provided that the criteria of indispensability and proportionality are respected.

Groupe Hyperion: a recognised player in Montpellier and across France

This feature on TF1 crowns several years of hard work to make Groupe Hyperion a benchmark in the field of private investigation. Based in Montpellier, we now have a network of agencies in several cities in France: Paris, Toulouse, Limoges, Annecy, as well as in Geneva.

Our team of CNAPS-licensed investigators works daily for businesses, individuals and legal professionals. Each assignment is handled with the same methodological rigour and the same respect for the legal framework as the one presented in the TF1 report.

This media recognition does not change our approach: we continue to prioritise discretion, efficiency and the quality of the reports we produce. But it validates our positioning as serious, professional players in private investigation in France.
