Ali Ismail Korkmaz, 19, died Wednesday at the Osmangazi University Hospital in Eskisehir, Today's Zaman said. He was attacked by a group of people while trying to escape from police at a demonstration June 2.
The other deaths were demonstrators Ethem Sarisuluk, Abdullah Comert and Mehmet Ayvalitas, and police officer Mustafa Sari.
The protests were in response to a government plan to create a replica of Ottoman military barracks in the place of Gezi Park in Istanbul.
Protesters' anger was fueled when police violently stopped a sit-in demonstration at Taksim Square May 31.
