Additional director-general of police (law and order) G.P. Singh visited Sonari in Charaideo, where an improvised explosive device exploded on Republic Day on Monday, to take stock of the situation.
Singh said the explosion was triggered by the banned militant outfit, United Liberation Front of Asom (Independent).
The official added that the persons who triggered the explosion are being identified and action will be taken against them.
Singh said, “Ulfa (I) has been doing such things for a long time and police have been taking action against them accordingly. It is a game of cat and mouse.”
The police earlier detained 17 people for interrogation from Upper Assam’s Dibrugarh and Charaideo districts in connection with the blasts on Monday. However, none of them have been arrested.
Ten persons were detained by Dibrugarh police and another seven by Charaideo police.
Five low-intensity IED bomb blasts rocked the three Upper Assam districts during the Republic Day celebrations.
Two blasts — at Graham Bazar near a garbage dump along National Highway 37 and at AT Road next to the boundary wall of Sikh National School at Marwari Patty — occurred in Dibrugarh town around 8am on Sunday.
