The colonel was detained on Sunday, with a court remanding Yazici on Wednesday.
The decision was made by Turkish prosecutors.
A source speaking on condition of anonymity to Anadolu confirmed that Yazici was detained as part of an investigation into the coup attempt.
The coup attempt was suppressed early Saturday morning, leaving nearly 300 people dead and hundreds more injured. In the wake of the attempt, Ankara has targeted tens of thousands of individuals suspected of being involved.
