On 1 November, the army told the Prime Minister that it had previously intercepted a message from Calcutta one week before the incident that said: "Attack Guwahati." The army told the PM that had known about the impending terror strikes in the western Assam towns for six weeks and had tried to prevent them. Lt. Gen. B.S. Jaswal, of the GOC 4 Corps, told the PM the army had received "non-specific" information on September 17 about possible strikes in Guwahati, Barpeta Road and Kokrajhar. CM Gogoi, who heads Assam's unified command that includes the army, corroborated the message with Singh. In admitting such knowledge he added that the government did not anticipate the scale of the blasts. The government then also formed a special team, headed by the inspector-general of police (special task force), R. Chandranathan, to probe the blasts and issue a report within 30 days.

Daimary, believed to shuttle between Bangkok, Manila and Singapore, is said to have authorised the attacks to signal a frustration with the lack of progress in talks between the NDFB and the Indian government. Following this, the Indian government decided to clamp down on the organization and other regional outfits. A ban on the NDFB, set to expire in 2008, was extended by two years. The Cabinet Committee on Security also decided to re-impose a ban on the outlawed ULFA, Hynniewtrep National Liberation Council (HNLC), however it spared the ANVC.

On 12 November, a Bhutanese man who lived in Nepal and fought against the monarchy was arrested for aiding the Assam attacks. Tenzing G. Zangpo, a senior leader of the Druk National Congress (DNC), a formation by Bhutanese exiles in Nepal, was picked up with the "home secretary" of the NDFB, Sabin Boro, from a rented house at Japorigog in Guwahati. An unknown source was quoted as saying, "After interrogation, both of them were arrested this morning on the charge of being part of the conspiracy behind October 30 blasts." The arrest attention from Bangladesh based forces to Bhutan for the first time since the probe was initiated. Police said the DNC claimed to be a political outfit opposing the alleged discrimination of Bhutanese people of Nepali origin by the monarchy since the 1990s.
