Following a failed coup attempt in July 2016, the Turkish government has launched a massive crackdown with mass detentions and arrests, as a result of which more than 600,000 people have been investigated to date on terrorism or coup charges and nearly 30,000 are still in prison.

In recent years there has been a significant change between the number of inmates in pre-trial detention and those convicted of a crime. While out of the 128,000 people in Turkey’s prisons in 2011, 27.8 percent were in pre-trial detention, the figure fell to 14 percent in 2014 but increased to 32.2 percent in 2016.
