At least 40 people were on Thursday injured, 18 of them seriously, when a cycle bomb ripped through a market in Howraghat town in central Assam's hill district of Karbi Anglong.
The Karbi Longri National Liberation Front (KLNLF) detonated the bomb at 12.45 pm in the busy Howraghat vegetable market on Netaji Subhash Road.
Eighteen seriously injured persons had been referred to Nagaon civil Hospital in neighbouring Nagaon district. Others were discharged after first aid.
The police had received intelligence inputs that the KLNLF had plans to launch a series of explosions in the district at the behest of the ULFA with which it has close links, the sources said.
Two KLNLF militants were arrested by security forces on Tuesday. Jiten Hansie was nabbed from Manja area with a Chinese grenade while the other, Kangpura Rongpi alias Rang Rongpi, from Diphu.
