NDFB anti-talk faction chairman and 2008 Assam serial blasts mastermind, Ranjan Daimary, was on Tuesday remanded to judicial custody by the Guwahati TADA Court.
Daimary was asked to be produced in the court again on September nine for further orders.
Daimary was brought to Guwahati on Tuesday from Goalpara jail and incarcerated in the Guwahati Central Jail in connection with plotting the serial blasts killing nearly 100 people.
Daimary alias DR Nabla, who was hiding in Bangladesh, was handed over to the BSF by Bangladesh Rifles (BDR) on May 1 near Dawki international border in Meghalaya.
He had formed a militant outfit known as the Bodo Security Force on October 3, 1986, and later renamed it as National Democratic Front of Bodoland on November 25, 1994, to establish an independent 'Bodoland'.
The NDFB had entered into a ceasefire agreement with the government on May 25, 2005 only to flout the ground rules. The NDFB had split into two factions - one for ceasefire and peace talks under B Sungthagra alias Dhiren Boro and the anti-talk hardliner faction led by Ranjan Daimary. The split had followed the serial blasts on October 30, 2008 in which Daimary was named as the mastermind by the investigating agencies.
The underground group maintains close links with the ULFA, even going for joint subversive activities, the NSCN-K, ANVC and KLO.
