A Customs and Border Protection dog sniffed out nearly $100,000 in drugs hidden in a cruise ship equipment locker.

The drugs were found in a locker on Royal Caribbean's Enchantment of the Seas cruise ship in Baltimore on Saturday, according CBP officials.

Narcotics canine Bak found two packages of heroin that weighed a total of one pound, eight ounces, and a 14-ounce package of cocaine on the ship.

CBP spokesman Steve Sapp said authorities don't know whom the drugs belonged to and no one has been arrested. The drugs were found in an area off-limits to passengers, he said.

The agency conducts random checks on cruise ships, but targeted Enchantment of the Seas because drugs had previously been found on the ship.

CBP will work with ship security officers to vet employees and passengers to determine if anyone on board had previous drug convictions or ties to drug-smuggling areas and might be responsible for the cocaine and heroin, Sapp said. But he said that task is difficult on cruise ships, which can have hundreds or thousands of employees.

The ship returned to Baltimore Saturday after a 12-day cruise that included stops in Labadee, Haiti; Samana, Dominican Republic; San Juan, Puerto Rico; Charlotte Amalie, St. Thomas; Philipsburg, St. Maarten; and Tortola, British Virgin Islands, according to Royal Caribbean spokeswoman Cynthia Martinez. She said the company was cooperating with investigators.
