US Customs and Border Protection authorities recently seized the entire ship on which they discovered a whopping 20 tons of cocaine last month — the largest vessel seizure in the agency’s 230-year history, according to a new statement.

Authorities executed a seizure warrant on the Fourth of July for the MSC Gayane, which was discovered with about $1 billion of the illicit substance on board on June 17, officials said in a Monday statement.

“Seizing a vessel of this size is an unusual enforcement action for CBP, but is indicative of the serious consequences associated with an alleged conspiracy by crewmembers and others to smuggle a record load of dangerous drugs through the United States,” Casey Durst, director of field operations for Customs and Border Patrol in Baltimore, said in the statement. “This action serves as a reminder for all shipping lines and vessel masters of their responsibilities under U.S. and international law to implement and enforce stringent security measures to prevent smuggling attempts such as this.”

When stacked end to end, the bricks of cocaine confiscated from the ship would stretch about 2½ miles, officials have said.

The initial raid happened after the ship sailed from Freeport in the Bahamas, The Hill reported. It began its voyage in Chile and had also stopped in Panama and Peru.

After the US stop, it was set to head to Europe, according to the report.

The MSC Gayane is owned by JPMorgan Asset Management and chartered to the Mediterranean Shipping Company, based in Switzerland.

“MSC is assisting and cooperating in any possible way with the authorities and is not the target of the investigation,” the shipping company said in a Tuesday statement.

“Drug trafficking is a serious issue which impacts the entire shipping and logistics sector,” the statement continued. “MSC remains grateful to the government officials in the U.S. for their proactive work and has offered its continued support, building on a longstanding track record of good cooperation with the authorities.”
