A Turkish financial crimes report has detailed on Monday extensive property transactions, multimillion-lira bank transfers and vehicle purchases involving the family and close associates of Alihan Kuriş, the alleged leader of a criminal organization under investigation by Ankara prosecutors.

The report by Türkiye’s Financial Crimes Investigation Board (MASAK), dated Aug. 20, was prepared as part of an investigation by the Ankara Chief Public Prosecutor’s Office into alleged laundering of criminal proceeds, fraud causing losses to public institutions and violations of the Tax Procedure Law.

Prosecutors requested an examination of changes in the wealth and assets of Kuriş and his relatives since Jan. 1, 2016.

MASAK examined assets, bank transactions, vehicles, company partnerships and property transfers involving Kuriş, his wife, parents, brother and grandmother, as well as his wife’s parents and sibling.

According to the report, land registry records showed a combined 1,818 property transactions involving four family members.
