The hours-long gang rape and beating of a 23-year-old female student on a bus in New Delhi sparked outrage throughout India. Police say 6 men raped the woman and beat her and her companion with iron rods on a bus driving around the city before stripping them and dumping them on the side of the road on the night of Dec. 16, 2012. The woman died approximately two weeks later of her injuries. - AP

That attack has led to calls for tougher rape legislation and reforms of a police culture that often blames rape victims and refuses to file charges against accused attackers.
