Allegations that Turkish security services in Ankara continue to be behind the disappearances of civilians linked to Fethullah Gulen, the Pennsylvania-based preacher accused of orchestrating the failed 2016 coup, have resurfaced following reports that two men were hauled off in the capital in broad daylight.

Eyewitnesses reportedly saw two men with black bags over their heads being stuffed into a white van after a large group of armed men, possibly plainclothes security officials, raided an apartment building in Ankara’s Altindag district on Feb. 13. Their targets are believed to be Ozgur Kaya, a former schoolteacher, and Yasin Ugan, an accountant. Both men were affiliated with organizations operating within Gulen’s once sprawling network of schools, businesses and other entities that are now shuttered in Turkey. They have not been heard from since.

Kaya’s wife Aycan said she became aware of her husband’s plight when an anonymous caller contacted her via WhatsApp the night of his disappearance. Kaya’s relatives rushed to the neighborhood where the incident occurred and spoke with residents who claimed to have witnessed the affair.

“I went to all the police stations in the area asking whether my husband had been detained, but they all claimed to know nothing of him or his whereabouts,” Aycan told Al-Monitor. “I am worried for his life. My nine-year-old twin sons believe their father is dead.”
