Two co-owners of the Antalya-based Delphin hotels have been put in pretrial detention as part of an investigation into the Gulen movement.

Media reported Friday that A.C. and his wife M.C. were arrested mainly on accusations of the membership to the movement.

According to the media, A.C. was a board member of the now-closed Antalya Entrepreneurial Businessmen Association (AGID). He spent 13 days in police custody over similar charges also in 2016.

The other two owners, identified as U.C. and E.G, were briefly detained before being released on judicial control during trial period.

Delphin hotels consist of 5 five-star hotels in the resort province of Antalya.

The Turkish government blames the Gulen movement for the July 15, 2016 coup attempt while the group denies role. Law enforcement have detained more than 160,000 people and jailed some 80,000 over links to the Gulen movement since the summer of 2016.

Meanwhile, more than 1,000 companies with a total value of $12 billion in assets have been seized and then transferred to Turkey’s Saving and Deposit Fund (TMSF) since the coup attempt on July 15, 2016.
