There is cancer in his lungs and in his bones and he has to use a walker to get around, but Özgür Doğan, a Turkish literature teacher, has been held in prison on terror and coup charges for months.

According to pro-Kurdish HDP Deputy Ömer Faruk Gergerlioğlu, Mr. Doğan was fired from his job by a government decree (KHK) issued after a coup attempt in July 2016 and then later arrested over alleged links to Turkey’s Gülen group.

“Özgür Doğan was a literature teacher and fired with a KHK. He is stage 4 lung cancer. He has not yet been referred to the forensic medicine. How many more cancer patients will die in prison,” Gergerlioğlu tweeted.

According to the Kronos news portal, Mr. Doğan lost at least 15 kg in prison over the past several months.

Turkish government survived the attempt that killed over 240 people and wounded more than a thousand others, however; AK Party officials along with Erdoğan pinned the blame on the Gülen group and launched a widespread war on its alleged and real followers.

The Gülen group denies any involvement in the attempt.

Several other cancer patients died in Turkish prisons in the past two years. Tacettin Toprak, 36, is the latest of them. He was laid to rest on Saturday in his hometown of Manisa.
