The case was initially registered at the Rajbagh police station in Kathua on May 29 and was re-registered by the NIA on July 30.
The NIA on Thursday carried out searches in five districts of Jammu and Kashmir in connection with its investigation into the dropping of weapons by Pakistani drones along the International Border, an official said.
According to police, the module was in operation for over two years and was involved in collection and ferrying of weapons and explosives dropped via drones from the Pakistani side along the International Border.
