A Turkish court Wednesday remanded in custody 60 businesspeople over alleged links with the Gülenist Terror Group (FETÖ), which is accused of orchestrating a military coup attempt in July 2016.

A total of 110 people were brought before the court as part of an investigation into FETÖ run by the Istanbul Chief Public Prosecutor's office.

Among the 60 suspects remanded are the brother and son of the former head of the major Turkish company Boydak Holding.

The remaining 50 people put on remand face charges of being FETÖ members and providing financial support to the terrorist group.

The court also released the remaining 50 businesspeople but imposed travel bans on them.

On Jan. 5, the Istanbul Chief Public Prosecutor's office issued detention orders for 380 business figures accused of providing financial support to the terror network, led by U.S.-based Fetullah Gülen.

The Istanbul Police Department launched simultaneous operations across 35 cities to apprehend the suspects and detained 164 people. Fifty-four were later released earlier under judicial control. Some 110 suspects are known to be abroad.

In a related development, 84 suspects, including on-duty military officers were arrested as part of an investigation into the Turkish Armed Forces in the wake of the coup attempt.

All suspects were users of Bylock, an encrypted messaging app exclusively used by the terror cult's members. The latest arrests bring to the total number of officers arrested in the investigation to 315, with the suspects to face charges of being FETÖ members.

Istanbul prosecutors have already ordered a roundup of 575 officers, including those based in Istanbul and assigned to other cities in the earlier stages of the investigation.

Some 36 officers were released after they invoked a law granting parole in return of confessions. Furthermore, four military officers wanted by prosecutors have fled abroad.
