The bomb at Ganeshguri was planted in a car and took place about 100 meters from Chief Minister of Assam Tarun Gogoi's official residence.

A spontaneous bandh total shut down, was observed the next day at Kokrajhar on a call given by the Vishva Hindu Parishad (VHP), the Bharatiya Janata Party (BJP), and the Bajrang Dal,[15] while schools and educational institutions also remained closed in Guwahati.

He would meet the Assam Governor Shiv Charan Mathur and Chief Minister Tarun Gogoi, as well as visit the Gauhati Medical College and Hospital to see the injured in the blasts.

[19] The Union home secretary, Madhukar Gupta, said a team of National Security Guards experts from New Delhi also visited the blast sites at Ganeshguri, the deputy commissioner's office and Fancy Bazaar.

A high-level team consisting of senior Home Ministry officials also visited Assam to make an on-the-spot assessment of the situation arising out blasts.

Asib Mohammed Nizami and Zulfikar Ali were the owners of two vehicles in which the bombs were planted in the Ganeshguri area of Guwahati and Bongaigaon.

Jaswal, of the GOC 4 Corps, told the PM the army had received "non-specific" information on 17 September about possible strikes in Guwahati, Barpeta Road and Kokrajhar.

Police were quoted as saying a text message sent to a local television station claiming responsibility for the bombings on behalf of the hitherto unknown Islamic Security Force-Indian Mujahideen turned out to be a hoax.

Interrogation of suspects linked to the fabrication of the car-bombs led investigators to believe that there were orders to initiate the operation by the NDFB founder-chief, Ranjan Daimary, as early as September.

Daimary, believed to shuttle between Bangkok, Manila and Singapore, is said to have authorised the attacks to signal frustration with the lack of progress in talks between the NDFB and the Indian government.

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.

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.

[24] Union Minister Shakil Ahmed hinted that communal riots in Assam for the preceding several days could be inter-linked to the attacks.

[10] Fresh evidence put forth by the Assam Police now suggests that the National Democratic Front of Bodoland (NDFB) engineered the attacks based on orders issued by its founder and chief, Ranjan Daimary, in September 2008.

This also proves the total failure of the government in combating terrorism", adding that it was likely that illegal Bangladeshi migrants in Assam, with an increasing influx of such immigrants, could be involved in the blasts.

He claimed that due to the sincere efforts of the ruling central coalition government, incidents of terror in the northeastern sister states had gone down by as much as 50 per cent in the last four years.

"[15] Former Indian prime minister Atal Behari Vajpayee hinted at a call for greater national unity and what he termed a collective war on terror after the blasts.

The Jharkhand government also came out strongly condemning the serial blasts, while having summoned a cabinet meeting in Ranchi for the next day to discuss the security situation in his region.

Additional security forces were rushed to assist in combing operations to track down those responsible for the blasts attempting to flee from Assam through the border with north Bengal.

State's Home Secretary, Ashok Mohan Chakavarty, said an alert had been sounded across West Bengal, with security tightened in the capital city.

In a message to Indian President Pratibha Patil and Prime Minister Singh, he expressed his indignation at the "barbarous" act and called for strict punishment for those responsible.

He said: "I learnt with deep indignation about the series of coordinated terrorist acts in Assam, which led to the deaths of scores of innocent people.
