Turkey has issued arrest warrants for a further 1,112 people allegedly linked to the banned Gülenist movement, as the impact of the failed military coup in 2016 has been felt throughout the country.
Announced on Tuesday by the Turkish state news agency, the operation is one of the largest ever, targeting supporters of cleric Fethullah Gülen, a former ally of President Recep Tayyip Erdoğan, who is now living his self-imposed exile in the US coup attempt.
Against Gülen followers of a "big operation" was off, said the Interior Minister Süleyman Soylu on Sunday. "We'll do it," he said.
Since the failed coup d'état in 2016, at least 77,000 people have been arrested and some 130,000 others have been fired from government agencies in the police, judiciary, science and other public sector bodies, as the Turkish government wants to cleanse state institutions of what it means to clean Gülenist Efforts for a "parallel state".
Hundreds of private companies have been shut down or are de facto under the control of the government, and almost all of the country's media are closely associated with the government.
The new arrests were made in an investigation into alleged falsification of trials in 2010 for police officers seeking promotion to the rank of deputy inspector, the Anadolu Agency reported. The prosecutors said Gülen supporters had asked questions in advance.
The arrests focused mainly on the capital, Ankara, although 124 people have been detained in 76 provinces so far, the Ankara Procurator's Office said.
It was not immediately clear how many of the target groups currently serve police officers.
Gülen has denied involvement in the coup attempt in July 2016 by rogues of the military, in which Turkish commandos attacked a resort where Erdoğan was staying. The president fled to Istanbul, but 250 people died in the ensuing chaos.
Turkey repeatedly resisted the extradition of the cleric from his home in Pennsylvania in Washington.
Critics say Erdoğan has used the post-coup two-year state of emergency as an excuse to suppress his increasingly consolidated control of the country.
Many of these powers were therefore included in new presidential executives after a referendum on constitutional changes in 2017, which according to Amnesty International was conducted in an "atmosphere of fear".
