A 60-year-old man, Umar Muhammed, was arrested while conveying firearms across the country.
The suspect uses his vehicle to transport rifles concealed in the bonnet compartment from one location to another, authorities say.
According to the Force Public Relations Officer, CP Frank Mba, the suspect uses his age to beat security checks since the African tradition gives respect to those advanced in age.
The suspect told the Police that he mostly helps Fulani nomads convey their rifles.
A group of kidnappers identified as Muhammed Bello, 52; Umar Abubakar, 22; Usman Mohammed, 20; Musa Ibrahim, 53; and Lawal Ismail, 25, have been linked to the suspect.
Meanwhile, the FPRO assured that the Police would be more thorough and discreet in conducting searches on the elderly.
