Filippos Kabouris is at the center of a financial review covering withdrawals of some 2 million euros and the use of safe deposit boxes. The sums under scrutiny clash with the income he declared for 2025, which stood at just 9,500 euros. That gap has become the focal point of questions about where the cash came from. Investigators are also combing through agreements for artist appearances at venues that may exist mainly on paper. Such outlets are being treated as possible shell companies set up to move money behind a wall of contracts. Tracing the real parties behind those deals is likely to decide how the case develops. The examination adds to the scrutiny now falling on Greece's live events sector, where opaque booking arrangements have drawn fiscal attention before.
