Celal Celik, a judge-turned lawyer representing the main opposition Republican Peoples’ Party (CHP) leader Kemal Kilicdaroglu, was detained at his home in Ankara on Friday.

The detention was carried out as part of an Istanbul-based investigation into the Gulen movement over its alleged role in stopping the National Intelligence Agency (MIT) trucks that were suspected of illegally transporting weapons to Syria in 2014.

Turkey survived a military coup attempt on July 15, 2016 coup attempt for which the government accused the movement, too. The Gulenists denies involvement in the abortive coup.
