A team of the National Investigation Agency has reached the terror attack spot in Kokrajhar in Assam, where at least 13 people were killed and several injured on Friday, after gunmen shot at security forces and civilians at a busy market place.
The NIA sleuths from Guwahati have been asked to study the crime scene and collect evidence, sources said.
The NDFB is suspected to be behind the attack even as the group has denied any linkages with the strike.
While no move has been initiated so far for a central probe, the fresh terror case may be handed over to the NIA in the coming days if the evidence points towards links with previous attacks carried out by the NDFB in Assam, which are already being probed by the central investigating agency.
In 2015, the home ministry had asked NIA to probe the killings of tribals by NDFB in twin districts of Assam-Sonitpur and Kokrajhar in December of 2014.
More than 70 tribals were killed by NDFB's militants in one of the biggest strikes carried out by the outfit. Four cases were registered by the Assam police which was later handed over to NIA.
