ANKARA, Nov. 27 (Xinhua) -- A businessman known as the "money vault" of the Gulen Movement has been escorted back to Turkey from Sudan on Monday, state media reported.

Memduh Cikmaz, allegedly a senior figure with interests in petrol retail and brick production, is accused of giving millions to the movement run by U.S.-based cleric Fetullah Gulen, who Ankara claims orchestrated the failed coup attempt on July 15, 2016.

Cikmaz was captured in a joint operation involving Sudanese intelligence after the Turkish National Intelligence Organization located him two months earlier, security sources told Anadolu news agency.

The report said MIT had created a team of specialists to locate suspected Gulenists abroad.

Turkey accuses Gulen, who has lived in the United States since 1999, of orchestrating the abortive putsch in July 2016. Gulen has denied involvement and condemned the coup attempt.

More than 50,000 supporters of Gulen have been arrested over suspected links to the cleric since the coup attempt.

Ankara also accuses Fethullahist Terror Organization of being behind a long-running campaign to overthrow the state through the infiltration of Turkish institutions, particularly the military, police, and judiciary.
