Indians have reacted with outrage after passersby watched a woman being stabbed more than 20 times on a busy street in the capital, Delhi. CCTV footage showed a man on a motorcycle approach schoolteacher Karuna, 22, who died in the attack. He is seen stabbing her repeatedly as people walk by, before hitting her on the head with a stone and kicking her. Locals did eventually intervene when he tried to escape. Police say they have charged the suspect with murder, BBC reported. During the attack, at least one man does try to approach the assailant but backs off after being threatened and is seen leaving the scene. Many others stop to see what is happening but fail to help. "It seems that the assailant started liking her when they used to be neighbors earlier, but since he was married, she never paid attention," said a senior police official. Local media had quoted the victim's brother as saying the assailant had a history of harassing his sister and the family had filed a police complaint against him. Images of the murder and the fact that many passersby did not stop to help the victim have caused outrage.
