The Istanbul Chief Public Prosecutor’s Office said on 22 September 2026 that police had carried out simultaneous operations that day at 13 addresses in eight provinces. The addresses were in Istanbul (2), Ankara (1), Kocaeli (2), Karabük (2), Denizli (3), Gaziantep (1), Kayseri (1) and Samsun (1). Nine suspects were taken into custody.

According to the statement, “FETÖ” directed its members’ marriages “according to organisational criteria” to ensure loyalty and continuity. It says this worked through people it calls “izdivaç sorumlusu” or “izdivaççı” (marriage coordinator).

“Izdivaç yapılanması” (“marriage structure”) is a term used by Turkish prosecutors for what they allege is a Gülen movement network in which designated “marriage coordinators” match members for marriage, a practice prosecutors present as a way of maintaining loyalty to the organisation.

The prosecutor’s statement says these coordinators collected candidates’ age, education, profession, hometown, family background, physical characteristics, organisational position and photographs. It says they used this information to build “candidate pools”, matched people on that basis, and also worked through groups on digital platforms.

The prosecutor said the 13 suspects were identified from the digital materials of a person, named only by the initials M.D., who was detained on 5 May 2026. Prosecutors “assess” M.D. as the organisation’s marriage coordinator.

The statement does not name the offence under investigation. The conduct it describes is the collection of personal information and the arranging of marriages.

On 15 September, the Ankara Chief Public Prosecutor’s Office announced a separate operation over what it called the “Kamu Mahrem İzdivaç Yapılanması” (“public-sector covert marriage structure”). Police detained 26 of 28 people sought in 15 provinces, and on 19 September a court remanded 15 of them.

On 15 September, Ankara prosecutors announced an operation over marriages among alleged Gülen movement members. On 22 September, Istanbul prosecutors announced another.
