At least 38 people in 5 different Turkish cities were detained for alleged links to the Gülen group, which is accused by the government of being behind a failed coup in Turkey last year, on Friday.

Turkish media reported that the suspects were rounded up over their alleged use of the ByLock application, which Turkish authorities believe is a communication tool among Gülenists.

Police carried out simultaneous operations in the provinces of Adana, Gaziantep, Şanlıurfa, Kayseri and Konya targeting followers of the group to apprehend a total of 38 people for whom detention warrants were issued.

Tens of thousands of people, including civil servants, police officers, soldiers, businessmen and homemakers, have either been dismissed or arrested for using ByLock or having accounts at the now-closed Bank Asya since the failed coup attempt on July 15, 2016.
