A businessperson told an Istanbul court that he paid TL 10 million ($210,000) in bribes and was forced to hand over two plots of land worth TL 50 million while trying to collect hundreds of millions of liras owed to his company by the Istanbul Metropolitan Municipality (IBB) and its affiliates.
Serbülend Danış, owner of Danış Asfalt, made the allegations during a hearing in a corruption case involving jailed Istanbul Mayor Ekrem Imamoğlu and other defendants.
Danış said he had previously told prosecutors that he was pressured into making payments while seeking to collect about TL 500 million in receivables stemming from contracts with the municipality's Road Maintenance and Infrastructure Coordination Department and affiliated companies.
During the hearing, Danış accused former Republican People's Party (CHP) Party Assembly member Baki Aydöner and his brother, Bulut Aydöner, of taking two plots belonging to him under the pretext of helping him collect the outstanding payments.
"Baki and Bulut Aydöner forcibly took two of my plots and victimized me," Danış told the court, rejecting claims that he had contacted them because he wanted to enter politics. He said he planned to file a compensation lawsuit against the defendants.
Adem Tuncay, a former IBB advertising management official who cooperated with prosecutors under Türkiye's effective remorse provisions, also testified at the hearing. Tuncay alleged that CHP-linked individuals visited him in prison and questioned him about his family circumstances.
He also claimed that after his release, he was not reinstated to his position and that his wife, who had worked for the municipality for 13 years, was dismissed.
On Wednesday, a total of 414 defendants, including suspended Mayor Imamoğlu, appeared before a judge at the 78th hearing in a corruption case involving the IBB. Fifty of the defendants are being held in pretrial detention.
Separately, Gözdem Ongun, the wife of former IBB official Murat Ongun, defended financial transactions prosecutors have cited in the case. She denied wrongdoing and said transactions totaling about TL 6 million through her company, BYZAG, stemmed from sales of jewelry and prayer beads.
The corruption investigation into Imamoğlu, was completed with a 3,809-page indictment filed on Nov. 11, 2025.
Prosecutors allege that Imamoğlu, identified in the indictment as the leader of a criminal organization, committed offenses including establishing an organization to commit crimes, bribery, money laundering, fraud causing losses to public institutions and organizations, unlawfully recording, obtaining and disseminating personal data, concealing criminal evidence, obstructing communications, damaging public property, accepting bribes, publicly disseminating misleading information, extortion by a public official, laundering assets derived from crime, bid-rigging, intentionally polluting the environment and violations of Türkiye's tax procedure, forestry and mining laws.
Prosecutors are seeking a prison sentence ranging from 828 years and two months to 2,352 years for Imamoğlu over 142 alleged acts.
