Late on Tuesday night,the Union Home Ministry issued direction to the National Investigation Agency to take over the probe into the blasts at Bodhgaya. The NIA is using the method of DNA tracing in the unexploded bombs to identify the suspects. The method was used by the US authorities after Boston bombing in April.
Sources said that a few suspects have already been rounded up for questioning and DNA test will help the agency confront them.
Union Home Minister Sushil Kumar Shinde and Union Home Secretary Anil Goswami are slated to visit Bodhgaya Wednesday. Shinde is likely to meet Bihar Chief Minister Nitish Kumar and state government officials to take stock of the situation. The NIA team is also likely to give a briefing on the probe so far.
The preliminary report given by the NIA to the MHA suggest the involvement of a local hand in the attack. Few persons have been picked up and they are being examined. One person,identified as Vinod Mistry who was questioned by the NIA Monday,is under watch. We have sought some clarification regarding his movement and antecedents, said a NIA official.
The agency said that the CCTV footage collected from 16 CCTV cameras installed at the temple complex have not been of much help. An NIA official added that only one footage contained recordings of explosion and movements of suspects. The footage is being investigated,he said.
A joint team of Bihar Police and NIA has examined some clock suppliers in the area to trace the origin of the timer used in the bombs. Lotus brand analogue timer were found in the live IEDs.
