Police have detained a total of twenty seven Turkish soldiers in six provinces as part of an investigation into the Gülen group, which Turkish authorities blame for a failed coup last year.

According to the Posta daily, a Kocaeli court issued detention warrants for 32 soldiers as part of an investigation by the Kocaeli Chief Public Prosecutor’s Office. Twenty-seven out of those were taken into custody in simultaneous raids in Kocaeli, Van, İzmir, Ankara, Bursa and Muğla early Tuesday.

Twenty-five out of the 27 detainees were on active duty, while two of them were suspended after the failed coup on July 15, 2016 over their links to the group.

The Gülen group and its leader Fethullah Gülen deny any involvement in the attempt, yet; Turkey’s ruling Justice and Development Party (AKP) government and President Recep Tayyip Erdoğan launched 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.

According to a tally by TurkeyPurge.com, nearly 146,000 people, including some 10,000 soldiers, have been dismissed from government jobs, more than 122,00 detained and almost 57,000 arrested over links to the movement.
