Akin Öztürk was among the 2,839 military officials arrested on 16 July 2016 as part of a large Turkish government crackdown on individuals possibly responsible for the 2016 Turkish coup d'état attempt on 15 July 2016. Hürriyet newspaper reports that he was accused of being the leader of the coup attempt. Although the semi-official news agency Anadolu stated, initially, that Öztürk confessed to a prosecutor that his intention was to execute a coup, this news later disappeared, and according to the private broadcaster NTV, Öztürk denied any involvement with the coup plotters. In his statement to the prosecutor, he claimed that he happened to be on the airbase visiting his grandchildren and, having learned of the coup attempt, successfully dissuaded the plotters from continuing with their plans and personally rescued two senior, loyal officers who were being held at the base.
