Mysterious incident on July 16

One of the events that still maintains its "mystery" about the coup attempt perpetrated by the Fethullahist gang is what Mehmet Dişli, with his major general rank, experienced on the day of July 16, 2016, when he was on duty at the Chief of Staff headquarters. He is also the brother of ruling Justice and Development Party (AKP) deputy chair Şaban Dişli. 

We also know that Mehmet Dişli seized Chief of General Staff Gen. Hulusi Akar, took him to the Akıncı Air Base in Ankara, told him to lead the coup and threatened him with a gun. 

There is also another thing we know; and that is a very mysterious situation. When the coup was suppressed and the chief of general staff and his team at the Akıncı base were saved, Akar took a helicopter to the Çankaya Mansion. 

Ever since the construction of the palace ended, the Çankaya Mansion has been used by the Prime Ministry. There was a crisis management center set up there and the prime minister headed the situation from that center. 

Mehmet Dişli was among the soldiers who got off the helicopter that brought Akar to Çankaya Mansion. Mehmet Dişli worked in this crisis management center at the Prime Ministry for about seven hours. While he was informing his brother on the phone, he was detained by policemen and later a court had arrested him. 

This is the "mystery." 

Akar boarded a helicopter together with a soldier he personally knew that was a putschist. After they arrived in Çankaya, Akar also overlooked that the coup plotter worked for seven hours at the crisis center.
