The conspiracy involved members of the BKI module based in various countries and was hatched on the directives of Pakistan-based BKI chief Wadhawa Singh Babbar by Germany-based accused Harjit Singh alias Laddi and Kulbeer Singh alias Sidhu, it said.
The NIA, which took over the investigation in the case from Punjab Police on May 9, had earlier chargesheeted Kulbeer, Laddi, Wadhawa Singh along with arrested shooters Mandeep Kumar alias Mangli and Surinder Kumar alias Rikka.
The anti-terror agency’s investigations so far have revealed that Laddi and Sidhu had recruited members into their terror gang and provided them with logistical support, funds and arms to carry out the targeted killing.
The probe has further revealed that accused Sonu, a native of Nawanshahr (Punjab), had played a crucial role in transferring funds into India and arranging weapons for the crime. Along with Laddi and accused Kulbeer Singh of Yamunanagar (Haryana), Sonu had provided funds to arrested accused Dharminder Kumar alias Kunal for the procurement of the weapons used in the crime. Kunal, hailing from Uttar Pradesh and residing in Ludhiana, had procured the weapons from a supplier in Madhya Pradesh.
The NIA investigations have further revealed the role of another weapons dealer in the case in addition to other foreign-based associates of the accused persons.
