On Monday, the agency intercepted a truck containing 661 illegal pump-action rifles.
Hameed Ali, NCS’ comptroller general, had vowed that the officers who cleared the 40-foot container where the weapons were found, would be punished.
Customs later issued a statement, declaring Abdullahi I, with service number 44483 ASC, and Odiba Haruna Inah, with service number 133386, wanted.
They were reported to have absconded after the weapons were discovered.
“The above customs officers are wanted in connection with the clearance of a one-by-40-foot container no PONU/825914/3 found to contain 661 pump-action rifles,” read a statement signed by Dan Ugo, spokesman of the service.
“Whenever/wherever seen, they should be arrested and taken to the nearest customs formation.”
Earlier, Ali had revealed that the agency had arrested three other suspects: Oscar Okafor, Mahmud Hassan, and Sadique Mustapha in connection with the illegal arms.
