Police said the teenager saw one of his friends being beaten and stepped in to intervene. The group then allegedly turned on him and assaulted him repeatedly. He sustained multiple blows and collapsed shortly afterwards. He was rushed to a nearby hospital, where doctors declared him dead. Superintendent of police B Nikhil said preliminary findings suggested the violence erupted suddenly....
