Turkish police teams on Wednesday detained at least 43 individuals on accusations that they use a smart phone application known as ByLock, Turkish media reported.

In Kayseri, a total of 26 people, including public servants, lawyers and housewives were detained on Wednesday, according to the Milliyet daily. Four others are still being wanted by the police.

The detainees are as follows: C.I., A.H., M.Ş., A.Ç., Y.K., B.Ş., C.S., F.G., F.Ö., İ.Y., İ.V., M.S., T.B., M.N.Y., R.Ö., Z.K., H.M.A., F.P., A.Ö., Ş.M., B.A., E.C., T.S., Ş.Ç., O.Ş. and B.Z.

In İstanbul, 6 people including former Eyüp deputy governor, were taken into custody by police as part of an investigation into the Gülen group, which is accused by the Turkish government of masterminding a failed coup attempt on July 15, 2016.

In a similar vein, police detained 11 people in Yozgat on accusations that they use the same smart phone application known as ByLock.

The detainees are as follows: N.Y, A.E, D.K, M.A, O.K, E.Ö, E.A, F.Ş, İ.K, M.Ö. and Ş.D.

Turkish authorities believe using ByLock is a sign of being a Gülen follower as they see the mobile phone application as the top communication tool among the group.

Tens of thousands of civil servants, police officers and businessmen have either been dismissed or arrested for using ByLock since the failed coup attempt.

The military coup attempt on July 15 killed 249 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 and initiated a widespread purge aimed at cleansing sympathizers of the movement from within state institutions, dehumanizing its popular figures and putting them in custody.

Turkey’s Justice Ministry announced on July 13 that 50,510 people have been arrested and 169,013 have been the subject of legal proceedings on coup charges since the failed coup.
