At least 32 teachers who were earlier dismissed from their posts were taken into custody as part of an investigation into the Gulen movement, which the government accuses of masterminding the July 15 coup attempt, on Friday.

Kayseri police raided homes of the teachers in question who are accused of having used ByLock, a smartphone app that Turkish authorities claim to be the top communication tool among Gulen followers.

Turkey has already detained more than 120,000 people over alleged or real ties to the movement.
