Turkish authorities have detained Sebahattin Şirin, a leader of Galatasaray's main supporter group UltrAslan, and his son, according to reports from Milliyet and other Turkish outlets. The detention follows a financial investigation by MASAK, Turkey's financial crimes investigation board, which has reportedly traced significant money movements linked to the pair.
Milliyet reports that the MASAK report uncovered a financial trail involving the father and son. NTV Haber, citing the same investigation, puts the volume of the tracked money flow at 51 million Turkish lira. The exact nature of the transactions and the specific allegations against Şirin have not been detailed in the available reporting.
The detention is part of a broader operation that has drawn attention to the inner workings of one of Turkey's most prominent football fan groups. According to Mynet, Şirin shouted slogans supporting Abdullah Öcalan, the imprisoned leader of the Kurdistan Workers' Party (PKK), while in custody. The outlet also reported that he has since been referred to a courthouse for formal proceedings.

Odatv.com notes that the operation is the latest chapter in the group's history, which has included previous police actions and controversies since its founding. The group has long been a powerful force in Turkish football culture, but its leadership has periodically faced legal scrutiny.
The case now moves to the judiciary. The key question is whether prosecutors will file formal charges against Şirin and his son based on the MASAK findings, and whether the financial investigation will expand to include other figures connected to the supporter group.
