A Turkish school official, who was deported from Myanmar over his ties to the Gülenist Terror Group (FETÖ), has arrived in Istanbul, a police source said Saturday.

Speaking on condition of anonymity due to restrictions on speaking to the media, the source said Muhammet Furkan Sökmen was a senior member of FETÖ, which Ankara has accused of orchestrating last July's coup attempt in Turkey which killed 250 people and injured nearly 2,200.

The source added that the so-called "Myanmar imam" -- a term the group uses to describe a senior member responsible for a specific branch of the terror network -- was a director at the Horizon International Schools, and a partner of the Mediterranean International Education Services Co. in Myanmar both linked to the FETÖ.

Sökmen was deported from Myanmar on Wednesday after the Turkish government canceled his and his family's passports.

Upon his arrival at Istanbul's Atatürk International Airport on Saturday, Sökmen was taken to the police headquarters for questioning, the source said, adding the suspect would later be referred to a court of justice.

Earlier this month Malaysia deported three Turkish nationals wanted by Ankara over alleged ties to FETÖ.

Turkey has asked several countries worldwide to shut down dozens of schools, colleges and businesses linked to the FETÖ network in the wake of the putsch attempt.

The terrorist group boasts a large network of schools in every continent and is accused of gaining new recruits to its cause through students trained at the schools.
