Last month after the Presidential referendum won by President Erdogan, Turkish authorities have detained more than a thousand people suspected of having links to Mr Fethullah Gulen.
People were arrested from all of Turkey’s 81 provinces and targeted the network’s structure in the police force.
Turkish authorities have arrested almost 50,000 people since the failed coup, including some 10,000 police officers and 7,500 military personnel, and sacked or suspended 120,000 others from a wide range of professions including soldiers, police, teachers and public servants
There has been mounting criticism of the extra ordinary arrests of such a large number of people overwhelmingly civilians who are accused of plotting the failed military coup.
Mr Gulen has emphatically denied any involvement with the coup attempt.
