NDFB had established 12 camps on the Bhutan-Assam border. During 2003-2004, the Royal Bhutan Army destroyed these camps as part of its Operation All Clear. NDFB chief Ranjan Daimary was offered amnesty by the Assam Chief Minister Tarun Gogoi in December 2003, but rejected the offer. On 8 October 2004, the NDFB announced a six-month-long unilateral ceasefire, that came into effect on 15 October. However, the Government continued its operations against the group. On 15 April 2005, NDFB extended the ceasefire. The Government released its general secretary Govinda Basumatary to open a channel of communication with the organisation's Bangladesh-based leadership. This resulted in a ceasefire agreement between NDFB and the Government on 25 May 2005. The agreement stated that the NDFB agree to cease hostile action against security forces and civilians. In return, the security forces would not carry out operations against the group's members. The agreement also stipulated that NDFB members would disarm and live in camps protected by the military for a year, and would refrain from assisting other militant groups. The pact came into force on 1 June 2005. However, certain factions of NDFB continued militancy. In May 2006, five members of the security forces were abducted and killed by suspected NDFB members in Assam's Udalguri district. The group also continued to clash with cadres of the ex-BLTF (Bodo Liberation Tiger Force). On 5 June 2006, two former BLTF cadres were killed by NDFB militants in the Karbi Anglong district, and one former member of the disbanded group was lynched by suspected NDFB militants in Golaghat district on 3 June 2007.
