The inside of the tubers were dug out and stuffed with cocaine. The tubers were then coated with sand.
The unsuspecting man thought it a bad idea to deliver tubers of yam coated in sand, and decided to wash the sand off.
As he washed the sand off a tuber with water, he found it was leaking
from the top. With all of the sand out, he found wraps of cocaine
inside the tuber.
