A huge cache of arms, including AK-47 rifles, belonging to insurgent outfit DHD(J) was unearthed in central Assam's North Cachar Hills district, police sources said on Saturday. A joint team of police and Army recovered 48 assorted weapons buried in a jungle at Thana Lambra in Haflong police station late on Friday night following interrogation of arrested Dima Halam Daogah (Jewel Garlosa) faction commander-in-chief Niranjan Hojai. The recoveries included 28 AK-47 assault rifles, eight SLRs, five M-16 rifles, two M-21 rifles, three pistols, one OG rifle and a grenade launcher, the sources said. During interrogation by National Investigation Agency (NIA) which recently arrested him from Indo-Nepal border, Hojai gave the lead to the buried arms in the jungle. Meanwhile, Jewel and 12 others were produced in a local court here yesterday in connection to the multi-crore rupee NC Hills Scam and they were remanded to 14 days police custody. The ethnic underground group DHD-J had unleashed violence in the hill district targeting trains particularly to demand a separate "Dimaraji" state.
