As a result of the findings made within the scope of the investigation, detention orders were issued for 27 suspects, including Erdal Celal Aksoy, Deputy Secretary General of IMM, Burak Korzay, General Manager of İsfalt, Hakan Bahçetepe, Mayor of Gaziosmanpaşa, Utku Caner Çaykara, Mayor of Avcılar, Kadir Aydar, Mayor of Ceyhan, Oya Tekin, Mayor of Seyhan, Ozan İş, Deputy Mayor of Beşiktaş, and Erhan Daka, Deputy Mayor of Avcılar, for the crimes of 'receiving bribes', 'giving bribes', 'irregularity', and 'interfering with the tender process.'

A detention order has been issued for 9 suspects, including Mandacı and Özdemir, on charges of 'fraud to the detriment of public institutions' and 'forgery of official documents.'
INVESTIGATION INTO THE BIGÇEKMECE MUNICIPALITY As part of the corruption investigation against İBB, an investigation was initiated after some suspects made various allegations against Büyükçekmece Mayor Hasan Akgün. It is claimed that the Mayor and officials forced construction companies operating in the district to make donations or sponsorships to villas, apartments, or the so-called 'Büyükçekmece basketball team' during the construction permit and occupancy permit process. It was alleged that they did not grant construction and occupancy permits to business owners who refused these demands. Some business owners were reportedly forced to accept the demands of municipal officials due to the pressure they faced. In the heavily constructed area of Büyükçekmece, it was claimed that Mayor Akgün's relatives managed excavation works in the district, profiting by dumping excavated materials in illegal areas and exerting influence. A detention order has been issued for 5 suspects, including Büyükçekmece Mayor Hasan Akgün and Deputy Mayor Ömer Kazancı. It has been learned that search, seizure, and detention operations are ongoing for a total of 47 suspects who have been issued detention orders.
