Police raid Katerini planning office over alleged ring involving staff, arrests reported

The raid

Officers from the Hellenic Police Internal Affairs Service, widely known as the 'Incorruptibles', searched the planning office (Polydomia) in Katerini on the morning of Monday, 2 November 2026. According to in.gr, one floor of the building was sealed off, and only the teams carrying out checks were allowed inside. Officers examined case files and documents linked to the inquiry while searches of the premises were under way.

Who was arrested

Reports disagree on how many people were arrested. Several outlets, including SKAI and Kathimerini, cited at least five arrests, while NEWS 24/7 and a later NewsIT report put the figure at three. According to in.gr and NewsIT, the detainees include the director of the planning office, a department head and a female employee. One NewsIT report also said that planning officials and private engineers were among those arrested.

Origin of the probe

Greek public broadcaster ERT reported, as cited by in.gr, that the operation began after a complaint about illegal construction. Outlets describe the case as an investigation into an alleged ring with possible involvement of office staff. Investigators are gathering and assessing evidence to establish how far the case extends, what unlawful acts may have taken place inside the agency and what role each person played.

What remains open

No charges have been disclosed, and the nature of the complaint has not been detailed. Police have not yet said which offences the detainees may face. Official announcements from the Hellenic Police are expected, and the investigation remains ongoing.
