Meanwhile, forensic experts who analysed the debris from the scene of blast indicated that Ammonium Nitrate was the main ingredient. Investigators were seeking the help of Information Technology experts to extract a better visual from the CCTV footage.
The footage in Bangalore showed a man taking the escalator and walking towards Platform No. 3, from where the train departed, sources said.
“Since he was carrying a bag, it is possible that there was another person who either boarded the train in Bangalore or the following stations. We are seeking the assistance of IT experts to improve the quality of images found in the CCTV footage,” a CB-CID official said.
