DW BUREAU The arrest of a murder accused last week blew the lid off a Pakistan-sponsored drugs and arms smuggling racket, following which three others, including a BSF constable, were held, the Punjab Police said on Monday. The Border Security Force (BSF) constable, Sumit Kumar, is a resident of Punjab's Gurdaspur district. He was posted along the International Border in Jammu and Kashmir's Samba sector and was apprehended on Sunday, the police said. Three others ? Amanpreet Singh, Simarjit Singh and Manpreet Singh ? have also been arrested in the case, they said. Foreign-made weapons, including a 9 mm pistol along with 80 live cartridges (etched with Pakistan Ordinance Factory markings) and two magazines and two live cartridges of 12 bore gun, and Rs 32.30 lakh in drug proceeds were recovered from Constable Sumit Kumar alias Noni, Director General of Police (DGP) Dinkar Gupta. Jalandhar (rural) police arrested Amanpreet on July 11 in a murder case. During investigation, he disclosed that he and his brothers were in touch with one Shah Musa from Pakistan for smuggling of narcotics and weapons across the India-Pakistan border, the DGP said in a statement here. Amanpreet told police that he and his brothers came in contact with Shah Musa through Manpreet and a BSF constable posted along the border in Jammu and Kashmir. Earlier, during the trial of a murder case, Sumit was lodged in Gurdaspur jail, where he had come in contact with Manpreet, according to the statement. Manpreet further introduced Amanpreet, Simarjit and Sukhwant to Sumit. The conspiracy to smuggle drugs and weapons from across the border was hatched in the prison, Gupta said. (editor@dailyworld.in)
