The Nigeria Customs Service, Ogun Area Command, said it had seized 1,401 bags of rice and three used cars within the last one week.
The goods were reportedly smuggled into the country from the neighbouring Republic of Benin.
The Controller of the Area Command, Sani Madugu, disclosed this on Friday at the Idiroko border office of the command.
According to him, the vehicles intercepted are Mercedes Benz C220, Toyota Tundra pick-up van and a Volkswagen Golf car.
Also impounded were 17 motorcycles used as means of conveyance of smuggled rice.
Madugu said within the period under review, 29 kegs of vegetable oil, two sacks of second-hand clothes and one sack of used shoes were also seized.
He gave the total duty payable value of the total seizures as N30.3m.
He said the seizures of the rice were made through the creeks around Yewa River, small warehouses and dump sites in Ipokia and the environs.
He said, “The command will not relent in its fight to curtail smuggling in Ogun. The smugglers have attacked me and they have attacked my officers, but we will not relent.
“We will continue to make the terrain very difficult for them. We have the backing of the army, the police and the Department of State Services.
“We have mounted surveillance at the creeks and river banks; we are monitoring the activities of the smugglers. We allow them to bring the bags of rice into the small warehouses by the creeks and bushes and then we swoop on them.”
