The Nigerian Navy Ship NNS BEECROFT is said to have intercepted 32.9 kilograms of cocaine on the vessel MV Chayanee Naree.
The ship and its crew, which included roughly six Asians, were apprehended.
The narcotic drug was allegedly found in 30 slabs inside a bag kept in Cargo Compartment One of the vessel, which was said to have arrived from Brazil.
Naval operatives, based on solid intelligence from Interpol, were claimed to have been monitoring the vessel that left Santos, Brazil, on September 19.
The ship was originally discovered on October 1 about 250 nautical miles off the coast of Benin Republic, where it floated for nearly a week before sailing into Nigerian seas, according to reports.
Commodore Bashir Mohammed, Commander, NNS BEECROFT, told journalists at a joint press conference on Thursday that the interception was possible thanks to collaboration between the navy, Interpol, Nigerian Customs Service (NCS), National Drug Law Enforcement Agency (NDLEA), and the Nigerian Ports Authority (NPA).
He said the vessel was arrested by NNS EKULU upon entry into Nigerian waters, adding that the navy had trailed its movement through the FALCON EYE Maritime Domain Awareness system.
