Admitting that "security lapse" had led to the blast here that left 15 people injured, Assam Chief Minister Tarun Gogoi today said the Paresh Barua-led ULFA (Independent) was responsible for the act.
The ULFA (I) had carried out the blasts with the "help of outside agencies" in Paltanbazar area of the city, he said at a sidelines of a function here. Gogoi said there "must have been some security lapse otherwise yesterday's blast would not have taken place".
