A Turkish court appointed trustees Friday to take over the management of companies possessed by the Dumankaya family, the owners of one of Turkey's leading construction companies, who have alleged ties to the Gülenist terror group (FETÖ).

The 1st Criminal Court of Peace of Anadolu decided to appoint trustees as part of an ongoing probe into the terror group. Halit Dumankaya, executive director of the construction group, which sponsors Turkish football club Galatasaray, had appeared in a court hearings in May for providing financial support to FETÖ.

Turkey was rocked by the coup attempt, the third major attempt by the military to seize power in its history, on July 15. Coup plotters linked to FETÖ tried to overthrow the government and assassinate President Tayyip Erdoğan.

Troops loyal to the state, along with police units and thousands of unarmed civilians who stood in front of tanks and tried to convince soldiers to lay down their arms, succeeded in quelling the coup attempt. In the process, more than 230 people, the majority of them civilians, were killed and more than 2,000 people were injured.

Massive purges are still underway to weed out suspected sympathizers of Gülen within the bureaucracy, military, police, judiciary and politics.
