Bekir Bayram, a 72-year-old imprisoned Turkish man with heart disease, was pictured on Tuesday on the way the Isparta State Hospital for a coronary artery bypass surgery.

According to Turkish journalist Sevinç Özarslan, a second coronary artery stent was placed in to treat Bayram’s ischemic heart disease.

The Bold news portal reported in June that Bayram, who lost around 40 kg in prison, has recently “cried for help” over the phone from his lawyer to secure him a conditional release “for a several months.”

He has been held in prison since November 2017 over alleged links to Turkey’s Gülen group, which the government accuses of masterminding a coup attempt on July 15, 2016. The group denies any involvement.

Following the coup attempt, the Turkish government launched a massive crackdown on followers of the Gulen group under the pretext of an anti-coup fight as a result of which more than 150,000 people were removed from state jobs while in excess of 50,000 others were jailed and some 600,000 people have been investigated on allegations of terrorism.

Since the coup attempt, there have been many cases of people who died in jail, some suspiciously, because they were denied crucial treatment or subjected to maltreatment or acts of torture.
