Ali Özer, a 48-year-old doctor who was jailed due to his alleged links to the faith-based Gülen movement, has died of a heart attack in Çorum Prison.

Özer had been the deputy chief physician at Ankara Nallıhan State Hospital.

The doctor died at the Çorum Teaching and Research Hospital, where he was taken after suffering a heart attack in his prison ward.

Özer’s body was sent to the Ankara Council of Forensic Medicine for an autopsy.

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 (AKP) government along with President Recep Tayyip Erdoğan pinned the blame on the Gülen movement.

The movement denies any involvement.

There have been many cases of suicide and deaths in prison, some of which were found to be suspicious, of people who have been affected by the purge of Gülen movement followers.
