The agency also recovered skunk and cocaine weighing more than 843 kilogrammes.
NDLEA Director, Media and Advocacy Femi Babafemi announced the discovery in a statement issued on Tuesday in Abuja.
He said that the arrest was made as the offenders attempted to evade the frequent road interdiction efforts by officers of the Kogi Command of the agency.
“More than 356 kilogrammes of cannabis and various psychotropic substances were recovered.
“This is addition to the arrest of four major drug dealers, including the most notorious drug kingpin in Nasarawa State.
“His drug distribution tentacles cut across Kano State, Plateau, Benue and parts of the Federal Capital Territory, Abuja.
“Curiously, some quantities of cocaine were intercepted in Benue on July 8, July 9t and July 13.
“Indeed, the supplier was arrested with 29.17 grammes of crack cocaine.
“In another raid on July 13, the Benue command also seized some quantities of cocaine,” he said.
Babafemi quoted the Chairman, NDLEA, retired Brig.-Brig Buba Marwa, as commending the commanders, officers, and men of Kogi, Nasarawa State, and Benue commands of the agency.
He said Marwa charged them not to relent but remain resolute in their commitment to rid every community of illicit drug peddling.
