Charles Taylor was picked up at the last checkpoint before he was due to board a Delta AirLine on his way to Us.
According to security sources, he concealed the whitish substance weighing 15.5 grams in both sides of a briefcase he was carrying.
The security sources said Taylor told interrogators that he was traveling back to the United States after he has finished performing on his dubbed concert in Mexico, Pachuca.
He said because the trip was for only a few days he decided not to travel with heavy luggage and therefore bought the briefcase at the Pachuca, from roaming vendors.
Taylor said he did not know the briefcase contained the substance. Investigations into the case continue.
