Two children of Nejat Atilla Demirhan, a brigadier under arrest over coup charges for some time, have also been jailed.
A Mersin court ruled on the arrest Demirhan’s two children, T.D. and N.R.D, both university students, as part of an investigation into the Gulen movement, which the government accuses of masterminding the July 15 coup attempt, on Friday.
While an indictment prepared in the aftermath of the coup attempt seeks three consecutive life sentence for Demirhan and 28 other suspects, the brigadier’s children were put in pre-trial arrest for having used ByLock mobile application.
ByLock is considered by Turkish authorities to be the top communication tool among followers of the 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.
