A total of 12 health workers, incuding doctors, nurses and midwives were detained in Eskişehir as part of an investigation into the Gülen movement, which the government accuses of masterminding the July 15 coup attempt.

According to the pro-gov’t daily Karar, on Feb. 12, police carried out simultaneous operations in Eskişehir, Bursa, Giresun and Isparta provinces and took 11 doctors, 1 nurses, 1 dentist, 1 x-ray technician, 5 nurses and 9 other health workers into custody.

12 of those were arrested by a court on Tuesday and sent to jail for using a smart phone application known as ByLock.

Turkish authorities believe ByLock is a communication tool between members of the Gülen 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.

Turkey survived 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 (AKP) government along with President Recep Tayyip Erdoğan pinned the blame on the Gülen movement, inspired by US-based Turkish scholar Fethullah Gülen.

The movement denies the accusations.

More than 123,000 have lost their jobs, nearly 88,000 detained and some 43,000 arrested since the coup attempt.
