11 bank employees were detained in Ankara-based investigation into the Gulen movement, which the government accuses of masterminding the July 15, 2016 coup attempt, on Thursday.
Detention warrants were issued for 20 people who were earlier dismissed from their jobs at the central bank; the government-seized Bank Asya; the state-owned development and investment bank, Iller Bankasi; and the Development Bank of Turkey (TKB), another state-owned lender.
Ankara police carried out operations to detain the suspects over their use of ByLock, a controversial mobile application that the government claim to be the top communication tool among the members of the movement.
According to media, police were able to locate only 11 of the suspects by Thursday noon.
Turkish government has detained more than 120,000 people including in its crackdown against the movement since last summer.
