At least 115 people in Tekirdag province were detained over their alleged use of ByLock smartphone app, state-run media said.

According to Anadolu news agency, arrest warrants were issued for 127 people who allegedly used the application while police were able to locate 115 suspects during the operation.

Detainees included businessmen, journalists, imams, bankers, hospital workers, students, veterinarians, nurses, doctors, shopkeepers, and police officers, Anadolu said.

In the meantime, the Manisa Prosecutor’s Office issued arrest warrants for 250 individuals for alleged ByLock use on Saturday, with arrest warrants issued for 12 people in Mersin province for the same reason.

Out of 250, only 82 were detained as of Saturday night, according to media.

Turkish authorities believe using ByLock indicates membership in the Gülen movement, which President Recep Tayyip Erdoğan and the government accuse of masterminding a failed coup attempt on July 15, 2016.

Tens of thousands of civil servants, police officers and businessmen have either been dismissed or arrested for using ByLock since the failed coup attempt last year.
