The Turkish government has launched an investigation into 433 performers of all types for their support of the academics who signed a declaration on Jan. 11, 2016 denouncing curfews imposed in predominantly Kurdish districts in Turkey’s Southeast, the Cumhuriyet daily reported on Sunday.

According to Turkish media, a document signed by İstanbul Police Chief Haydar Özdemir says an investigation has been launched into 433 performers for “praising crime and criminals.”

In the document sent to the Performers Union, the İstanbul police demanded the identity and contact information for 433 performers.
