Another 63 police officers who were earlier dismissed from profession have been put under arrest over their alleged use of ByLock mobile application.
Turkish authorities believe ByLock is a communication tool between members of the Gülen movement.
The Istanbul-based investigation sought arrest of 72 former police officers, but the court in charge jailed 63 of them with the remaining 9 released on judicial control, on Friday.
Tens of thousands of civil servants, police officers and businessmen have either been dismissed or arrested for using ByLock. Critics, however, blast the government for detaining thousands simply for using a mobile application
Turkey experienced a military coup attempt on July 15 that killed over 240 people and wounded more than a thousand others. Immediately after the putsch, the Justice and Development Party (AK Party) government along with President Recep Tayyip Erdoğan pinned the blame on the Gülen movement.
