The youngest convict in an infamous fatal gang-rape on a bus in New Delhi three years ago has been released from a youth correctional facility, Indian police said.   The attacker was the youngest of a group of men who brutally assaulted a 23-year-old student on a bus in 2012, triggering global outrage and protests in India over the country's high levels of violence against women.
