Four persons were killed and 54 others injured when suspected militants belonging to the United Liberation Front of Assam lobbed a powerful grenade at a festive gathering of Mising tribe at Jonai town in Dhemaji district of North Assam late Saturday night.
Police informed that the grenade went off amid a 500-strong crowd that was celebrating the spring festival of the Mising tribe inside the premises of a local cultural centre.
Fourteen seriously injured persons, including two critically injured, were shifted to Assam Medical College in Dibrugarh.
Police launched a manhunt in the area to nab the culprits involved in the blast even as angry locals pounced upon a 16-year-old boy suspecting him to be the one engaged by the ULFA to hurl the grenade. The boy was seriously injured in the counter-attack.
The ULFA has rocked the state with a series of explosion in the run up to its 'Army Day' on Sunday, killing seven persons and injuring over 70
