"Both organisations (ANVC-ANVC.B) should take full responsibility to ensure that none of the cadres tend to turn rogue and become a factor which dilutes our efforts to achieve the objective of peace settlement," Sangma told reporters after the cabinet meeting here.
His statement came in the wake of reports alleging that one of the cadres of the outfits was found to have sold arms worth Rs 17 lakh to the banned Garo National Liberation Army (GNLA).
Stating that there were allegations of selling of arms by some of members of ANVC and ANVC.B, Sangma said "They are still under investigation."
"If one has to go by this particular incident (selling of arms), we cannot rule out that there are instances where one or two cadres of the organisation tried to hide their arms and not declare all of them," he said.
Stating that disbanding of the rebels organisation was just the beginning, Sangma said "Subsequently there are many other parameters which we need to fulfil."
