Turkey sent a diplomatic note requesting the extradition of Adil Öksüz, who the government says was the "imam" of Turkish air force personnel who last year bombed parliament as part of the attempt to topple the government.
Foreign Minister Mevlüt Çavuşoğlu said that Turkey submitted a formal note Wednesday demanding fugitive Adil Öksüz's extradition. Çavuşoğlu said: "If this person is there, we asked that he be located, taken into custody and returned to Turkey."
Öksüz, a member of U.S.-based Islamic preacher Fethullah Gülen, is believed to have played a key part in the failed coup. He was detained near an Ankara air base hours after the coup attempt, only to be released by a judge two days later and has been on the run since.
Turkish media have reported that he has been spotted in Frankfurt and Ulm and given a temporary residence permit by Germany's Baden-Wurttemberg state.
