When you need answers you cannot get on your own, a ντετέκτιβ is the person you call. In Athens, that means Petros Drolias — a licensed private investigator working from Aiolou 104, near Omonia station, with more than 30 years of experience, over 1,500 cases handled, and work in 14 countries. His office takes on private, corporate and digital investigations, and the first conversation is free, confidential and without obligation.

Who Is Petros Drolias?

Petros Drolias has worked as a ντετέκτιβ since the early 1990s, under licence number 4891/7/1/90-δ'. He handles every case personally, from the first discussion to the final report, supported by a network of associates across Greece and abroad. His clients include individuals, businesses, lawyers, insurance companies and shipping companies. Three decades of cases, no publicity — that is the office's record, and its rule is simple: only legal methods, only evidence that stands.

How an Investigation Works

Every case a ντετέκτιβ takes on follows the same six steps. First, a confidential discussion — you describe the issue, free and without obligation, at the office, by phone or by video call. Second, a legal check — the office examines whether the request is legal and feasible, and tells you honestly what can be done. Third, a plan and estimate — you receive a written action plan and a personalised cost estimate before any work starts. Fourth, field investigation — observation in public spaces, research in public sources and registries, and on-site investigation. Fifth, updates at predetermined points, with the plan adjusted if the facts change. Sixth, a written report — documented, with a timeline and material, ready for your lawyer to use.

What a ντετέκτιβ Handles

The office handles cases from infidelity and disappearances to corporate fraud, bug detection and evidence collection for court. Services include private investigations, corporate investigations, forensic investigations, online investigations, legal disputes, teen problems, electronic countermeasures and device monitoring. Each case gets its own plan — there is no fixed price list, because every case differs in duration, geography, number of investigators and required material.

What a Detective Can and Cannot Do

A serious ντετέκτιβ does not promise phone tapping or access to someone else's devices. Article 19 of the Greek Constitution protects the secrecy of communications, and illegally obtained evidence is not accepted by the courts — unlawful surveillance is punished under Article 370A of the Penal Code. What a detective can do is collect and verify real facts: observation in public spaces, research in public sources and registries, on-site investigations, and interviews with people willing to talk. Legally collected evidence can be used by your lawyer; the court makes the final assessment of its value.

Coverage and First Steps

The team works from the Omonia office, where a ντετέκτιβ covers all of Athens and Attica — the centre, the northern suburbs such as Kifisia and Marousi, the southern suburbs such as Glyfada and Palaio Faliro, the western suburbs, Mesogeia and Piraeus — and the whole of Greece, from Thessaloniki to the islands, with investigations abroad as well. The office answers 24 hours a day, seven days a week. If you need a ντετέκτιβ, the first step costs nothing: a free, confidential conversation, in person, by phone or by video call — and a written plan and cost estimate before anything begins.
