The official said that investigation has revealed that certain employees and ex-employees of Central Ordinance Depot (COD), Jabalpur (Madhya Pradesh) had conspired with a group of arms smugglers and had stolen a large number of AK series rifles, their parts and SLRs from the sheds of COD, Jabalpur.

"The king-pin of the racket, Purshottam Lal Rajak, an ex-armourer of the COD, had cannibalised serviceable parts from out of commission weapons and had manufactured functioning prohibited weapons such as AK-47s," the official said, adding 22 such AK-47 have been recovered so far.

"These weapons stolen out of COD Jabalpur were then supplied to arms smugglers from Munger which were then further supplied to Maoists and criminals."
