Turkish pianist Dengin Ceyhan was arrested on Tuesday for allegedly insulting President Recep Tayyip Erdoğan in social media posts.
He had been in detention since Feb. 14. Known for his criticism of the government, Ceyhan played the piano during the Gezi Park protests of 2013 and supported academics who had signed a peace petition. However, no details have yet been released on the nature of the messages that led to his arrest today.
Born in 1991, Ceyhan is teaching at the Hacettepe University conservatory.
