On June 18, CBP agents discovered 39,525 pounds of cocaine, nearly 20 tons, stashed in several containers onboard the vessel which was docked at the Philadelphia seaport.

The street value of the drugs was estimated at about $1.3 billion, making it the largest cocaine seizure by the agency.

“A seizure of a vessel this massive is complicated and unprecedented – but it is appropriate because the circumstances here are also unprecedented,” said US Attorney William McSwain. “We found nearly 20 tons of cocaine hidden on this ship.”

At least a half a dozen crew members have been arrested, according to Homeland Security Investigations. Charges included conspiracy to possess cocaine aboard a ship, reports BusinessInsider.

The investigation is ongoing.

The Gayane sailed under the flag of Liberia and had previously traveled through the Bahamas and several South American countries, according to an online ship tracker.
