A person, who drove a car packed with explosives into a business hub here, one of the nine serial explosions that ripped through Assam on October 30, 2008, was arrested by the CBI in Arunachal Pradesh on Thursday.

The arrest comes less than 24 hours after the CBI released photographs of nine terrorists linked to the blasts.

A CBI spokesperson said Rahul Brahma of the outlawed National Democratic Front of Bodoland (NDFB) was arrested in Zero, where he was taking shelter with his wife and child for the past few days.

“This is a major success for us, and we are hoping to catch a few more very soon,” Superintendent of Police N.S. Kharayat told IANS.

Brahma drove a Maruti 800 packed with explosives and parked the vehicle at a crowded business place at Panbazar. The explosion killed eight people and wounded up to 30. A total of nine near-simultaneous explosions rocked Assam that day, killing 100 people and wounding 500. All the blasts were blamed on the NDFB.

“Vital clues were given by NDFB chairman Ranjan Daimary during the nine- day interrogation [by the CBI],” the CBI official said.

Daimary, handed over to the Indian authorities by Bangladesh on May 5, is in the custody of the Assam police. Earlier he was in the CBI's custody for nine days, until Tuesday.

“Daimary has confessed to having masterminded the explosions and said the explosives were procured from Assam and also from Bhutan,” he said.

The CBI had filed a charge-sheet, naming Daimary and 19 more NDFB militants, for the serial blasts.
