Details of the investigation

The investigation, which involves 22 suspects, was initiated on charges of “bid rigging” and “forming, leading, and assisting a criminal organization.” On February 27, law enforcement detained Koseler and 21 other individuals as part of a wider operation by the Istanbul Financial Crimes Division.

Following legal proceedings at Beykoz Courthouse, 13 individuals, including Koseler, were remanded in custody, while 9 were released under judicial control.

Allegations against Koseler

Koseler, who denies the allegations, provided a statement to the prosecutor’s office, stating: “I have never engaged in discussions, pricing negotiations, or directives with representatives of companies bidding in municipal tenders.”

“If any irregularities exist, they should be thoroughly investigated, but I am not involved in any way. I have never given preferential treatment to any company or instructed any personnel to do so,” He further emphasized according to reports.

Mayor of Istanbul Metropolitan Municipality Ekrem Imamoglu criticized the decision of arrest on his social media account X and said, “Unfortunately, we are living in a period that will go down in history as the ‘Istanbul Lawlessness’. Our Beykoz Mayor Alaattin Koseler was also arrested. For the first time in history, 3 CHP district mayors of Istanbul have been arrested.”
