Mahmut Kış, a Turkish judge and a former Supreme court member, has died of heart attack, according to a tweet posted by his lawyer.

Kış was fired from his job with a decree issued by the Turkish government in the aftermath of a coup attempt in July 16, 2016. He was later sentenced to 7 years in prison over alleged links to the Gulen group, which the government accuses of masterminding the attempt. The group denies any involvement.

The Turkish government has arrested a total of 2,431 judges and prosecutors and dismissed 4,424 others since the botched coup attempt in 2016.
