A dreaded leader of the Manipur-based banned insurgent outfit UNLF, M J Joysing, was arrested along with two others in Guwahati on Thursday, officials said.
'Captain' Joysing alias Suresh Singh of the United National Liberation Front (UNLF) was picked up by a joint team of army and police from his rented house in Japorigog area, they said.
A woman cadre, who was used as a messenger was also caught along with Joysing, while another militant of the outfit was picked up from a private hospital where he was undergoing treatment, the officials said.
The trio were staying in the rented house for the last seven months for conducting subversive activities.
Several laptops, two mobile handsets and documents were recovered from the house.
The seized laptops provided information about the UNLF purchasing land in Guwahati for setting up a base in Assam, whereabouts of their leaders and some organisational inputs, the officials said.
Information about other Manipur-based underground groups setting up camps here also came to light during search operation, they said.
