MIAMI -

Federal customs agents say they have seized cocaine worth an estimated $2.7 million hidden in luggage at Miami International Airport.

U.S. Customs and Border Protection officials say 231 pounds of cocaine were found Thursday during a random search. The drugs were contained in three pieces of luggage that had arrived from Quito, Ecuador.

No arrests have been made and it wasn't immediately clear what happened to the owner of the bags.

CBP officers at Miami International Airport routinely pick out bags at random to be X-rayed. In this case investigators noticed irregularities in the luggage. When the bags were opened, officers found 90 brick-shaped objects hidden inside. The substance in the bricks tested positive for cocaine.
