Rapid Action Battalion recovered an astounding 41,000 bullets at Burungya Kalapani Pahar of Sherpur's Nalitabari upazila yesterday.

They also recovered three rifles, three parts of a heavy machine gun, two parts of an anti-aircraft gun, 10-15 machine gun bullets, 10 long- and short-range walkie-talkies, a sniper's optical scope and magazines stuffed in boxes inside plastic barrels.

The stash was buried underground in the barrels at a hill near the Indian border.

'Considering the location and all other circumstantial evidence it appears that the seized cache of arms and ammunition were of an Indian insurgent group,' said security analyst Maj Gen (retd) MA Rashid.

Asked whether those could have been left behind by the Pakistan army during the Liberation War in 1971, Rashid said there was slim possibility of that

According to sources in different law enforcement agencies, the Garo Pahar area in Nalitabari, had become a safe haven for Indian group United Liberation Front of Asom (Ulfa).

With the latest seizure by Rab-5, led by Lt Col Mahbub Alam and Company Commander Mobasserul Islam yesterday, law enforcers have found around one lakh bullets, arms, and explosives in this region in the last one decade.
