Former Police Chief Hanefi Avcı, who was sentenced to five years and seven months in prison on charges of aiding a leftist terror organization and its members and later released in 2014 by a decision by the top court, has released a new book on the Gülen Movement, which he alleges is behind his conviction. He said, in his new book, he tried to convey how the Gülen Movement should be perceived and what activities it could be engaged in as now, after his first book depicted how members of the movement carried out the alleged illegal activities in government institutions. He said the struggle with the structure cannot be won with only the police and judiciary and that opposition parties should exert efforts to solve the problem.

"This is the entire nation's problem. All segments of society, the state's other institutions, nongovernmental organizations and parties should cooperate in the struggle against the movement. The issue concerns the entire country," Avcı said. Noting that opposition parties also believe movement members should be removed from state institutions, said that the political struggles among parties should be detached from this particular issue and that they should all act together in fighting against it. When asked whether the Gülen Movement will be in control of state institutions, he said it was unlikely, yet their presence cannot be eliminated all at once.
