MUMBAI: For the first time for Indian Railways , a dedicated cyber cell is coming up in Mumbai where the RPF will use technology to probe theft and track down touts involved in unauthorized ticket booking. The cell, being set up by Western Railway, will likely be at Mumbai Central and have an RPF staff of 28.Passengers on premium trains like the Rajdhani are more vulnerable to high-value theft. Such passengers include traders carrying precious stones or people carrying ornaments. On long-distance trains leaving Mumbai at night, thefts are reported more frequently in Gujarat and MP as passengers fall asleep by the time their train enters these states.In many instances, culprits turn out to be co-travellers from the same coach holding a valid ticket. “Organized groups are involved in high-value theft.Last February, we busted four members of a Haryana gang for stealing jewellery and cash worth Rs 14 lakh from an NRI traveller's bag at Vadodara station,” said a crime branch officer.The foursome had offered help to the traveller to move her bags. During investigation, officers spotted on CCTV footage a man moving suspiciously at the station, which led to the bust. “Identifying suspects on CCTV footage isn't simple as one needs to study every frame in multiple videos. Cyber cell officers would be trained in what to look out for. Dossiers will be compiled on organized gangs,” said a senior officer.Mobile device forensics, including call data record (CDR) analysis and how to track a number from cellphone tower dump data, will be the prime focus of the cyber cell (see graphic for details). Cyber cell officers will also be trained on analyzing IP addresses, studying ticket booking data to analyze booking patterns and bank information analysis to track down touts.Unauthorized sale of tickets peaks in the holiday season. “Online booking starts at 8am and the highest chances of illegal software being used by touts occur in the next few minutes. Studying booking data is cumbersome, but the IP address or bank account used for booking serves as evidence in court,” an officer said.
