Editor at Yeni Asya daily newspaper, Nur Ener was arrested over her alleged use of ByLock, a smartphone messaging application that Turkish government claims to be the top communication tool among the members of the Gülen movement.

Held under custody at Istanbul’s Caglayan courthouse for three days, Ener was, on Sunday, sent to Istanbul’s Bakırköy Womens’ Prison for pre-trial detention.

Turkey already keeps more than 150 journalists under arrest.

Ener was first detained upon complaint of her old friend, known by initials M.B., who accused Ener to have used ByLock.

“[M.B.] called me later on to confess that he/she reported me to police in rage against others,” Ener testified before adding that M.B. has yet to locate “other” friends who, in fact, used ByLock.

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.

The movement denies any involvement.
