A 16-year-old girl was attacked with a knife and dragged by her hair on a road by a man she had refused to marry, in Chhattisgarh capital Raipur. The 47-year-old attacker has been arrested, the police said on Sunday. A video shows the man, Omkar Tiwari, dragging the badly wounded teen by her hair, holding in his other hand the knife he had stabbed her with late on Saturday evening. When the video emerged on a social media platform, the police launched an investigation.
