U.S. Customs and Border Protection officers seized approximately 214 pounds (97 kilograms) of cocaine concealed under a container ship arriving in San Juan, Puerto Rico on February 26.

The estimated value of the seized cocaine is $1.7m.

CBP officers discovered the narcotics concealed within a parasitic device attached to the hull of the vessel, which arrived from Rio Haina, Dominican Republic.

The seizure occurred during a routine vessel boarding, when officers deployed underwater drone technology to inspect the vessel’s hull.

“This seizure demonstrates the dedication and skill of our officers in utilizing advanced technology to protect our borders,” said Roberto Vaquero, director of field operations in Puerto Rico and the U.S. Virgin Islands. “Our continued collaboration with local and federal partners is crucial in disrupting the flow of illicit narcotics and safeguarding our communities.”

The San Juan municipal police dive unit assisted in recovering the device from the vessel. Homeland Security Investigations responded to support the operation.

The seized cocaine was transported for further examination and secured according to established procedures.

The investigation is ongoing.
