Twenty businessmen and educators were detained over alleged links to the Gülen movement, which the government accuses of masterminding the July 15 coup attempt, the TRT Haber news portal reported on Thursday.
Detention warrants were issued for 38 Bursa individuals early on Thursday. Hours later, police teams carried out simultaneous operations in Bursa province and detained twenty of them.
The detainees are accuse of having links to the Gülen movement, using of a smart phone application known as ByLock and attending public meetings organized by the movement followers.
Turkish authorities believe ByLock is a communication tool between members of the Gülen movement.
Tens of thousands of civil servants, police officers and businessmen have either been dismissed or arrested for using ByLock since a failed coup attempt last July.
Some of the detainees were reportedly dismissed from profession with recent decrees issued by Turkish government in the aftermath of the coup attempt.
