LUCKNOW, Sept. 26 -- The Lucknow Police on Thursday solved the gripping chain-snatching case that claimed the life of Atul Jain, 42, in Jankipuram last week. The investigation, which spanned five days and leveraged both advanced technology and coordinated police work, culminated in the capture of one of the accused, Arvind Kumar, 27, after an encounter in Gudamba, while his accomplice fled, said officials. The incident unfolded on September 20, when two men on a white motorcycle attempted to snatch Jain's gold chain near a number four intersection. Jain pursued the men on his scooter. According to eyewitnesses, two other youths on another motorcycle, believed to be the snatchers' accomplices, intercepted Jain, allegedly kicking his scooter and causing him to crash. Jain sustained fatal injuries as a result. Following a tip-off, the police laid a trap in Rajauli village on Thursday. When officers stopped a suspicious bike, the pillion rider, Arvind Kumar, opened fire. Police returned fire, injuring and apprehending Kumar, while his alleged accomplice, Sanjay Yadav, escaped, said DCP Shashank Singh. The accused was booked under Section 109 (1) (attempt to murder) of the BNS and sections 3, 25, 27 of the Arm Act. "What made the investigation extraordinary was the way technology was used to overcome weak evidence," said DCP East. According to Lucknow Police, a mobile data analysis was done wherein thousands of mobile numbers around the crime spot were scanned; suspicious numbers gave the first breakthrough. Then, CCTV surveillance was used as footage from over 500 cameras across Lucknow helped police identify the white bike. The motorcycle carried no number plate, complicating tracking. The suspects kept moving across different police zones, leading to joint operations. Also, the CCTV and mobile evidence were thin and fragmented. The duo frequently changed phones and hideouts to mislead police. However, teams from Crime Branch, DCP (north) and (East), Gudamba and Jankipuram police stations coordinated seamlessly to crack the case....
