The chairman of Turkey’s Naksan Holding who had been arrested over alleged ties to the Gülen Movement had his arm broken by detention officers, according to an anonymous source.

Police arrested 68-year-old Cahit Nakıboğlu and his son Taner Nakıboğlu –member of the holding’s board – as part of an investigation into the movement, which the government accuses of masterminding the July 15 coup attempt, on July 24.

A recent tip submitted to Turkey Purge has backed up earlier allegations that people detained or arrested following the coup attempt are being subjected to maltreatment, persecution, torture and even rape.

In the latest of such incidents, officers broke an arm of 68-year-old Cahit Nakıboğlu, the source who has recently met with a lawyer representing the conglomerate, told Turkey Purge on the condition of anonymity.

Turkey survived a military coup attempt that killed over 240 people and wounded a thousand others, on July 15. Immediately after the coup bid, the government along with the President Recep Tayyip Erdoğan have launched a widespread purge that aimed to cleanse sympathizers of the faith-based Gulen Movement from within the state institutions, dehumanize the popular figures of the movement and put them under custody.

A total of 81,494 people have been purged from state bodies, 40,029 detained and 20,355 arrested since the coup attempt. Arrestees included journalists, judges, prosecutors, police and military officers, academics, governors and even a comedian.

The Amnesty International said on July 24 that it gathered credible evidence that some detainees are beaten, tortured and raped, in official and unofficial detention centres across Turkey.
