At least 28 individuals were detained as part of two separate investigations into the Gulen movement, which the government accuses of being behind the July 15 coup attempt, on Thursday.

Detention warrants were issued for 21 people in a Nigde-based probe. While 14 of them have been rounded up in Nigde and Ankara so far, the detainees included university students, academics, small business owners and corporate executives. They are accused of having used ByLock, a smartphone app that Turkish prosecutors claim to be top communication tool among the movement supporters.

Meanwhile, 14 others were detained in a separate investigation in Izmir’s Seferihisar district the same day.

Turkey has already detained 113,260 people over perceived ties to the movement since July 15 while 47,000 were put under pre-trial arrest.
