Nikos Pelekasis & Associates has been active in the field of private investigations since 1980.

More than four decades of professional experience have provided the agency with extensive knowledge of different types of investigations and the practical challenges that may arise during the investigation of a case.

Over the years, investigative methods have changed significantly. Traditional field investigation remains important, but modern private investigations increasingly involve digital information, electronic devices, specialised technical equipment and the analysis of information from multiple sources.

Our approach therefore combines investigative experience with modern technology, selecting the appropriate methods and technical means according to the requirements of each individual case.

Private Investigators in Athens and Piraeus

Our agency maintains offices in two central locations in Attica:

Athens: 39 Stadiou Street, Athens, 10559
Piraeus: 36 Iroon Polytechniou Street, entrance from 8 Dragatsi Street, Piraeus Attica, 185310

From these locations, we undertake investigations throughout Athens, Piraeus and the wider Attica region.

At the same time, our network of associates enables us to handle cases throughout Greece when an investigation requires research, verification of information or fieldwork outside Attica.

We also cooperate with clients and professional partners from abroad who require reliable investigative assistance in Greece. Depending on the case, communication and coordination can be carried out remotely, while the investigation itself is conducted by our team or associates within Greece.

Private Investigations for Individuals

Private investigations may concern a wide variety of personal and family matters.

These can include infidelity and relationship investigations, missing or untraceable persons, family-related cases, verification of information, collection of evidence and other situations in which reliable information is required before important personal or legal decisions are made.

The circumstances surrounding personal investigations are often sensitive. For this reason, confidentiality and discretion are fundamental throughout the entire process, from the initial consultation to the completion of the investigation.

Information obtained during an investigation is handled according to the nature of the case and the applicable legal framework.

Corporate and Professional Investigations

Reliable information can also be particularly important when making professional or business decisions.

Our agency undertakes corporate and professional investigations for businesses, professionals, law firms and other organizations requiring information or investigative assistance in Greece.

Depending on the circumstances, an investigation may concern the verification of information, professional or corporate background research, internal matters, collection of evidence or other issues affecting the interests of a business or professional.

The purpose of such investigations is to provide the client with reliable and useful information that can contribute to informed decision-making.

Digital Investigations and Technical Services

Technology has fundamentally changed both the way information is created and the methods used in modern investigations.

For this reason, our agency combines traditional investigative experience with modern technical equipment and digital investigation methods.

Our technical services include TSCM counter-surveillance inspections, detection of hidden electronic surveillance devices, GPS tracker detection, mobile phone and computer security checks and investigation of suspicious digital activity, depending on the circumstances and legal framework applicable to each case.

Technical inspections may involve specialised equipment for detecting active or inactive electronic devices, radio-frequency transmissions and concealed components, combined with physical inspection and digital analysis where appropriate.

The purpose of these services is to identify suspicious devices, software or activity and provide the client with a clearer understanding of the findings.

TSCM – Counter-Surveillance and Bug Sweeps

The widespread availability of small electronic devices has made technical security an increasingly important part of modern investigations.

Our agency provides TSCM inspections and counter-surveillance services for offices, residences, vehicles and other spaces where there is a legitimate concern regarding unauthorised surveillance.

Depending on the circumstances, an inspection can include the use of specialised detection equipment and a detailed physical examination of the area.

The objective is to identify potentially suspicious electronic devices or installations and assess the environment for indications of unauthorised surveillance.

GPS Tracker Detection and Vehicle Inspections

Modern tracking devices can operate through different technologies and may be installed in various locations inside or outside a vehicle.

Our agency provides vehicle inspections for GPS trackers and other suspicious electronic devices, using a combination of technical equipment and physical inspection.

The exact inspection procedure depends on the vehicle, its electronic systems and the type of device that may potentially be present.

Both factory-installed electronic systems and aftermarket equipment must be taken into consideration during an inspection in order to distinguish legitimate vehicle components from potentially suspicious devices.

Investigation Equipment and Modern Technology

Modern investigative work increasingly requires specialised technology.

Our agency uses professional investigation and counter-surveillance equipment according to the requirements of each case. Technical tools can assist an investigator in detecting electronic signals, locating concealed devices, examining digital activity and documenting findings.

Technology, however, does not replace investigative experience.

Equipment must be selected and used according to the circumstances of each investigation, while the results must be interpreted within the broader context of the case.

For this reason, our approach combines professional experience, field investigation and specialised technical equipment rather than relying on a single investigative method.

Confidentiality, Discretion and Professional Investigation

Confidentiality is fundamental to the relationship between a private investigator and a client.

Information relating to the identity of the client, the circumstances of an investigation and the findings obtained during the course of a case is handled with discretion.

At the same time, every investigation has legal and practical limitations. The methods that can be used depend on the circumstances of the case and the applicable legislation concerning privacy, personal data and communications.

For this reason, each case is evaluated individually before the appropriate investigative approach is determined.

Our objective is not to make unrealistic promises, but to conduct each investigation professionally and provide the client with the most reliable information that can lawfully and reasonably be obtained.

Media Presence, Interviews and Publications

During its decades of activity, Nikos Pelekasis & Associates Private Investigation Agency and its representatives have been featured in television programmes, newspapers, news websites and other media outlets.

Nikos Pelekasis and Lefteris Pelekasis have participated in interviews, television reports and journalistic features concerning private investigations, security, technology and various issues of public interest.

The agency also maintains an archive of articles and publications covering both investigative and broader social topics.

These appearances and publications provide an additional record of the agency’s long-standing presence in the field of private investigations in Greece.
