A private investigator you can meet in person.

Arcadia Company does not look after Sesto San Giovanni from a distance: the agency's operational office is right here, at Piazza Don Enrico Mapelli 60. Anyone looking for a private investigator in Sesto San Giovanni can therefore meet us in person, in a private office, instead of describing their situation over the phone to someone they have never seen. For many people this is a decisive step: a suspicion of infidelity, a child spending time in risky circles or an employee with unusual absences are matters you would rather discuss face to face.
We have been an authorized investigation agency since 2017, holding a Prefectural License pursuant to art. 134 T.U.L.P.S., with a UNI EN ISO 9001:2015 certified management system and FEDERPOL membership. We operate in compliance with the GDPR and the profession's Code of Ethics, and every assignment ends with a technical report designed to be produced in court by the client's lawyer.
Why the office matters: the first consultation
The first meeting is free and protected by professional secrecy. It serves to clarify three points: whether there is a legally protectable interest (without which the law does not allow us to accept the assignment), whether an investigation can really produce useful evidence, and how much it would cost. The consultation can take place at our office or remotely, but for those who live or work between Sesto, Cinisello Balsamo and Cologno Monzese, dropping by the office is often the simplest and most discreet option.
Being on the spot also has an operational advantage. When observation has to start close to an event already known, such as an appointment, a shift change or the return from a business trip, planning and start-up happen from the same base, without having to cross the city.
Sesto San Giovanni and the Court of Monza
Few people know this: although it is part of the Metropolitan City of Milan, Sesto San Giovanni falls within the district of the Court of Monza, together with Cinisello Balsamo, Cologno Monzese, Cusano Milanino, Paderno Dugnano, Carugate, Solaro and Vimodrone. A separation, a request to review maintenance payments or an employment case involving residents or companies in Sesto are therefore often heard in Monza, not in Milan. The competent court nonetheless depends on the criteria set by law and should be identified with your lawyer: knowing it from the outset makes it possible to tailor the investigative report and delivery times to the proceedings in which it will be filed.
Investigations for companies in North Milan
For much of the twentieth century Sesto was one of Italy's industrial capitals, the city of Falck, Breda and Marelli. Today it is an area of offices, logistics, services and large sites undergoing redevelopment, and Milan's northern belt is where corporate assignments prevail. For businesses we carry out investigations into sick-leave fraud and absenteeism, abuse of Law 104 leave, moonlighting and shortages and theft in the workplace. In these cases evidence is built by documenting, in public places or places visible from outside, behaviour incompatible with the state of illness or with contractual obligations, without ever assessing how the employee actually performs their work: this is the boundary that case law draws for checks entrusted to an investigator.
Investigations for individuals and families
For individuals we handle marital infidelity for a fault-based separation, child custody and review of maintenance payments, as well as monitoring of minors and stalking. In every case the work stays within a precise perimeter: observation and documentation in the field, public registers (company, land and vehicle registries), open sources and documents provided by the client. An authorized agency does not install GPS trackers on someone else's car, does not access phones or accounts and does not acquire bank data: these are activities the licence does not permit, which would make the evidence unusable and would also expose the client to criminal consequences.
From Sesto to the rest of Lombardy
From the same office we operate in Milan and throughout the metropolitan area, in Monza and Brianza and in the provinces of Bergamo, Como and Varese; we also coordinate investigations throughout Italy. Details are on our territorial coverage page.
Costs and contacts
The cost of an investigation depends on the type of inquiry, the number of operators and the duration; close to our office, travel expenses are minimal. Every quote is free and agreed before starting: for an idea of the orders of magnitude, read how much a private investigator costs, or book a meeting at our office from the Contacts page.

Frequently asked questions.
Answers to the most common questions from people looking for a private investigator in Sesto San Giovanni: office, competent court, timelines and confidentiality.
Where is your office in Sesto San Giovanni?
At Piazza Don Enrico Mapelli 60, 20099 Sesto San Giovanni (MI). The first consultation is free and confidential and can take place at our office or remotely, whichever you prefer.
For a case in Sesto San Giovanni, does the Court of Milan or the Court of Monza have jurisdiction?
Sesto San Giovanni falls within the district of the Court of Monza, like Cinisello Balsamo, Cologno Monzese and other municipalities in the northern belt. However, the competent court for each individual case depends on the criteria set by law (for example the parties' residence or the place of work) and should always be checked with your lawyer.
Is the consultation at your office confidential?
Yes. What you tell us is covered by professional secrecy and your data is processed in accordance with the GDPR. You can let us know the contact details and times at which you would prefer to be called back.
Can a company in Sesto have an employee on sick leave checked?
Yes, if there is a concrete suspicion of wrongdoing, such as feigned illness, a second job or improper use of leave. The investigator documents behaviour in public places or places visible from outside; they cannot, however, check how the employee performs their work.
How quickly can an investigation start in Sesto San Giovanni?
After the consultation and the signing of the mandate, activities in the Sesto and North Milan area can be planned at short notice, often within 24-48 hours, even close to an event already known. Checks on public registers and open sources proceed in parallel.
Do you have a question?
The first consultation is always free and without obligation. We reply within 24 hours.
