The ‘cosmic room’ of the Turkish Army’s General Staff Mobilization Department is the name given to the archive where the military’s most classified secrets are held. In December 2009, police received an anonymous tip-off relating to an alleged plot hatched by elements of the military to assassinate then Deputy Prime Minister Bulent Arinc. As part of the investigation, public prosecutors entered the ‘cosmic room’ to ascertain whether any files relating to the plot existed. The prosecutors examined files in the room 22 times. The court case surrounding the plot was stalled and eventually dropped as investigators could not determine when or how confidential hard drives held at the facility were copied, and the alleged tip-off was never recorded.
The investigation was led by Kadir Kayan, a judge who had previously acquitted Fethullah Gulen of charges filed against him in 2005. During that case, Kayan had requested information from the security services regarding Gulen. The subsequent report was prepared by a police officer named H.D., the brother of a former editor of Gulen’s now defunct flagship publication Zaman. Likewise, the head of the team who conducted the searches was until recently a fugitive from the law. The overall prime suspect in the case is Muharrem Kose, a military judge now under investigation for involvement in the 15 July coup attempt.
