The gendarmerie commander of Trabzon's Maçka district, which has been an unusual target for PKK terrorists recently, was detained on Wednesday over his suspected links to the Gülenist terror group (FETÖ).

Lieutenant Zabit Zengin was taken under custody within the scope of a FETÖ probe in western İzmir province. His arrest warrant was demanded by a court in İzmir, and he was detained by Trabzon anti-terror police.

Maçka was shocked by an unusual terror attack on August 11, when PKK militants killed a child and a soldier.

Eren Bülbül, 15, and Sergeant Major Ferhat Gedik became victims of PKK terror.

The unusual terror attack raised questions, as PKK militants find no shelter in the Black Sea region in Turkey. FETÖ and the PKK have been reported to be in collaboration many times in recent years.Fourteen FETÖ members were found in the house of two PKK suspects who were detained as part of a terror probe in the western province of Manisa in February. According to obtained information, the PKK terrorists were going to help FETÖ members escape abroad.Meanwhile, a secret FETÖ informant in the southeastern Siirt province confessed that two PKK terrorists informed him of a coup attempt in Turkey that was due to take place. The informant claimed that two terrorists approached him on July 14, 2015, a day before the coup attempt, and told him that the president and the prime minister would be killed, and a coup attempt would be staged.A lieutenant arrested over his links to FETÖ, also revealed that the group helped him to enroll in a military school despite his links to the PKK.Batman Governor Ahmet Deniz told Anadolu Agency (AA) in August 2016 that there were some PKK radio recordings in which they called upon FETÖ terrorists and their own members to "embrace one another."
