The internal affairs unit of the Hellenic Police launched a sweeping anti-corruption operation across urban planning offices in the Attica region on Friday, arresting six people after a months-long investigation.

The operation targeted planning offices in the northern Athens suburbs of Maroussi, Galatsi and Kifissia, with officers conducting unannounced raids and inspections at multiple sites.

Six people were arrested on the spot under the flagrante delicto procedure: five civil servants and one private engineer. More than 30 individuals in total, are named in the case file.

Searches carried out at the homes, offices and personal effects of those detained yielded 334,895 euros in cash, along with computers, mobile phones, an external hard drive, personal organizers, handwritten notes and a safe deposit box rental agreement.

The investigation centers on allegations of bribery, irregular building permits and the legalization of unauthorized constructions. Charges vary by individual and include participation in a criminal organization, passive and active bribery, trading in influence, and breach of duty.

The operation remains ongoing.
