A week after the body of 40-year-old Dariyabai Shankarlalji Lachheta alias Chaudhary, was found inside the women's compartment of Bhuj Express on December 7, the Government Railway Police (GRP) got their first breakthrough — a visual of the suspect (from Borivli station) wearing the same clothes found at the scene of the crime. He can be seen boarding the train at Borivli.

An officer privy to the investigation said a red shirt and cap had been recovered from the spot. Police suspect that the accused boarded the train from Borivli, and after killing the woman, got off somewhere between Mahim and Matunga, because the train slows down on that stretch. Apart from questioning more than 500 ragpickers on the Surat-Churchgate line, the team has also shown the CCTV grab to over 1,000 scrap dealers in the area to trace the accused.
