The linkmen Dilung alias Dilam Marak alias Bipimom Marak (30), a person from the Garo community of Meghalaya, and Jyoticharan Boro were arrested from the remote Landakunda area on the border which is close to Bangladesh, Goalpara ASP (headquarters) Susanta Biswa Sarma said.
Apart from the IED which was defused by the Army's Bomb Defusal Squad, a remote control device and a bomb-making manual were also recovered, Sarma, who led the operation, said.
The duo are believed to be close to Drishti Rajkhowa, a close aide of anti-talk faction leader Paresh Baruah, he said.
