The chief of the National Democratic Front of Bodoland (NDFB), Ranjan Daimary, and nine other members of the outfit were sentenced to life imprisonment by a CBI special court on Wednesday in the 2008 Assam serial blasts case that had claimed 88 lives.

Amid tight security on court premises, CBI Special Judge Aparesh Chakraborty pronounced the quantum of punishment for Daimary, George Bodo, B Tharai, Raju Sarkar, Anchai Bodo, Indra Brahma, Loko Basumatary, Khargeswar Basumatary, Ajay Basumatary and Rajen Goyary.

Three other convicts — Prabhat Bodo, Jayanti Basumatary and Mathura Brahma — will be released after they pay a fine imposed by the court.

The CBI court has ordered the release of Nilim Daimary and Mridul Goyary in the case as they have already served their sentence.

As he was being whisked away by the police, the NDFB chief told reporters that he would appeal to a higher court against his conviction.

"Bodoland will be created as we continue to serve our jail sentence," he added.

His supporters, who had gathered near the court since morning, shouted slogans in favour of a separate Bodoland.

Daimary and 14 others were convicted on Monday under various sections of the IPC.

The NDFB chief's bail was cancelled immediately after his conviction and arrested, while the others were already in judicial custody.

Nine serial blasts were triggered by the NDFB on October 30, 2008 — three each in Guwahati and Kokrajhar, two in Barpeta and one in Bongaigaon — killing 88 people and injuring 540 others.

The CBI had taken over the case from Assam Police and had filed two charge sheets, naming 22 accused — seven of them still absconding.
