President Recep Tayyip Erdoğan has called on people to report sympathisers of Gülen Movement to police, accusing the movement of masterminding the July 15 coup attempt.

The movement has repeatedly denied any involvement in the attempt.

“You may have friends from within this community. I am asking you to uncover them. You need to report them to police and prosecutors. Why? This is our duty to the nation,” Erdoğan said in his speech during a meeting with businessmen on August 10.

Some 28,000 people have been detained and around 15,000 of them arrested as part of investigations into coup attempt since July 15.

Meanwhile, 75,000 state personnel were purged due to their alleged links to Gülen Movement.

In his initial remarks following the coup attempt, Erdoğan said the incident was a gift from God to cleanse up Gülen community.
