What is TRUE about Berkin?

The Turkish President Abdullah Gul has appealed for calm after police clashed with protesters angered by the death of a teenage boy, who was hurt during anti-government demonstrations last year. Berkin Elvan had been in a coma since he was hit by a teargas canister as he went to buy bread.
    The news of the 15-year-old Berkin Elvan’s death was announced earlier this morning. We lost our son, may he rest in peace, wrote his family on Twitter. As the news spread, people started gathering in front of the hospital where he spent 269 days in a coma. The police showed up, the crowd got angrier, and police intervened with pepper gas. Berkin’s story had become a symbol for Gezi Park protesters.
