PURI/BHUBANESWAR: Even as the National Investigation Agency (NIA) has got down to unravel the alleged terror links of Puri train coaches burning accused Ramachandran Subash, an 11-member team of the premier agency began examination of the charred bogies at Puri railway station on Saturday.
Led by investigating officer Prasant Kumar, the team inspected the burnt coaches to gather fresh evidence about the materials used to torch the trains.
While the first forensic team, pressed in by the Government Railway Police (GRP) from the State Forensic Science Laboratory, had found use of powdered substance, the NIA squad is looking for fresh clues.
The five forensic experts of the NIA examined the coaches while others took the case records from GRP and Railway Police Force (RPF). Following the arson, RPF and GRP had registered two separate cases and were investigating into it.
It was the RPF which made the breakthrough when two of its constables rounded up Subash and he was subjected to interrogation. RPF later collected hours of video footage and pinned down Subash.
During interrogation by investigating agencies like State Intelligence and NIA, Subash had allegedly confessed to carrying out similar arson in Haridwar and Howrah railway stations. His lie detection test also pointed at connections with terror modules operating in Mumbai.
On November 12, Subash had set fire to five sleeper coaches of four express trains at Puri.
