The Turkish Police on Tuesday detained 17 suspects over their alleged links to a network accused of orchestrating a coup attempt in 2016.

The Ankara Prosecutor’s Office said that an arrest warrant was issued for 29 suspects that were allegedly linked to the Gulen Movement, which the Turkish Government accused of attempting a coup on July 15, 2016.

The suspects were detained within the scope of the 2012 “Gendarmerie Sergeant Exam’’ fraud investigation, said a statement.

The statement noted that the members of the group accessed the exam questions before the written exam.

The 29 suspects include 26 persons who passed the written phase of the exam and three who mediated in the distribution of questions.

The Ankara-based operations had continued to detain the remaining suspects across 20 cities.

The Turkish government accused the group members of fraud in exams which it said the suspects used as a stepping stone for its infiltrators in the public sector.

The government also claimed that the members of the Gulen Movement at military schools helped their recruits pass the admission interviews.

Ankara accused U.S.-based Fethullah Gulen of masterminding the attempted coup in 2016, in which at least 250 people were killed.
