LAGOS: The Nigerian Security and Civil Defense Corps said on Monday (Tuesday in Manila) that it had arrested 19 people on suspicion of stealing oil in southern Nigeria's River State in recent operations against vandalism. The suspects were found on Friday and Saturday with three tanker trucks, a large wooden boat and many liters of petroleum products that were thought to be illegally made diesel, said Abu Tambuwal, head of Nigeria's paramilitary agency in the state. He said they made the arrests and seizures to support the state government's campaign against illegal refineries partly responsible for the soot pollution in the state.
