Amar Jyoti Kalita, the main accused in the Guwahati molestation case was arrested in Varanasi in Uttar Pradesh on Monday, three weeks after the shocking incident. Wearing a black and white check shirt, a clean-shaven Kalita has lost his smile in police custody. In the video aired by a news channel in Guwahati on July 9, the camera did not seem to bother Kalita - he smiled as he led a group of men who fell upon the victim, dragging her back when she managed to run a few feet in a futile attempt to flag passing cars for help.
