A 20-year-old man, who brutally murdered his alleged girlfriend in Delhi on Sunday, has been sent to the police custody for two days. The teen girl was stabbed 22 times by Sahil, and then crushed with a rock slab in a busy street of northwest Delhi's Shahbad Dairy area on Sunday evening. A new security camera footage, which is now going viral on social media, shows Sahil talking to a friend right before he killed the teen girl.
