The Assam government had received prior intelligence report of an attack by terrorists of NDFB-S but it did not know about the target and spots, said a senior official today.

Addressing a press conference, Assam Commissioner and Secretary (Political and Home) Prateek Hajela said, "There was information from the intelligence that NDFB-S would attack. But we did not know about the target and the spots."

The Centre has been claiming that the Assam government was informed about a possible strike by the anti-talk Songbijit faction of the National Democratic Front of Bodoland. Hajela said the security forces have intensified their operations to neutralise  NDFB-S and the state government has spoken to the Centre for all cooperation from Meghalaya and Arunachal Pradesh in flushing out the terrorists from their territory.
