Assam Police recently seized two vehicles carrying huge quantities of sophisticated arms and ammunitions and arrested four people near the state's Chirang District, close to the border with West Bengal.
Following the interrogation, it has been revealed that the arms were meant for a new underground Gorkha outfit.
The arms consignment was coming from Dimapur in Nagaland after being smuggled into India through Myanmar.
According to the police, the dealers have been supplying arms to insurgent groups based in the North East.
"We have arrested four people, two are drivers and other two are arm dealers from Dimapur. They have also been supplying arms to NDFB (S) outfit," said Chirang Superintendent of Police Ranjan Kumar Bhuyan.
International border in the North East has always remained an easy access for many foreign arms dealers and terror outfits into India.
