Mehmet Kaya, a former judge at Turkey’s Supreme Court of Appeals, was handed down a 15-year prison sentence on Tuesday for alleged membership in the Gülen movement, the state-run Anadolu news agency reported.

He also had served as the general secretary of the Board of Judges and Prosecutors (HSK).

Kaya, who was dismissed by government decree after a 2016 failed coup, was arrested in February 2018.

Turkey accuses the Gülen movement of orchestrating the abortive putsch, although it denies any involvement.

In the post-coup crackdown, some 600,000 people were the subject of investigation over terrorism links, and nearly 140,000 public servants were fired by government decrees.
