Cabir Duysak, a Turkish academic who was dismissed from his job with a gov’t degree in 2016, has died of stomach cancer at age of 41, according to the Bold news portal.

Duysak was a PhD candidate and a teaching assistant at the İstanbul University’ History department. He was dismissed from his job with the No.672 degree issued by the Turkish government in the aftermath of a coup attempt on July 15, 2016. He was later investigated over alleged links to the Gülen group, accused by the government of masterminding the attempt.

A Turkish prosecutor accused Duysak of having Bylock, an encrypted mobile app that Turkish government sees as a communication tool among followers of the Gulen group.

Since 2016, thousands of academics, judges, civil servants, and other professionals have been suspended, fired from their jobs.
