Hanefi Avcı (born 1956, Kahramanmaraş Province) is a former chief of police in Turkey,[1][2] and author of the best-selling book Haliç’te Yaşayan Simonlar, in which Avcı claimed that the Gülen movement had infiltrated the police and manipulated key trials such as the Ergenekon trials through judges and prosecutors close to the movement.
[10] In 2010 he published the auto-biographical book Haliç’te Yaşayan Simonlar: Dün Devlet Bugün Cemaat, which covered various aspects of the "deep state" in Turkey, including the Ergenekon organization and the Gülen movement's infiltration of the police.
Avcı's book claimed that the Gülen movement had highly placed people with privileged access to wire taps, and would publish information obtained this way when it suited it.
[14] In September 2010 Avcı was arrested and accused of links with the terrorist group Devrimci Karargâh, which he denies,[13] saying that he had "been expecting these kinds of defamations".
[3] In July 2013 Avcı was convicted of aiding a terrorist organisation and of trying to influence a trial with his book, and sentenced to 15 years 3 months.
