Indian Crew Member Dies In Custody After Portugal Seizes 5 Tonnes Of Cocaine From Ship

An Indian crew member arrested after Portuguese authorities seized five tonnes of cocaine from a Hong Kong-flagged container ship off Portugal was found dead in his cell in Lisbon on Wednesday, Aug. 5.

The man was one of three foreign nationals arrested during Operation Skydrop. Portuguese authorities had intercepted the container ship about 640 nautical miles (1,185 km) off the Portuguese coast and later escorted it to the port of Sines.

The cocaine was found hidden in void spaces on the ship. Portuguese authorities said the drugs were intended to be transferred at sea to other vessels before being taken to landing points along the Portuguese or Spanish coast.

The circumstances surrounding the crew member’s death are under investigation. Portuguese media reported that he was believed to have died by hanging, but authorities have not confirmed the cause of death.

The Directorate-General for Reintegration and Prison Services (DGRSP) said the man was being held alone in a cell at the prison facility next to the Judicial Police headquarters in Lisbon.

Prison officers found him at about 8 a.m. during the morning opening of the cells and immediately called the emergency services through 112. Medical personnel arrived and confirmed his death.

The body was taken to the Institute of Forensic Medicine at 11:40 a.m.

The DGRSP said the cell was closed after the discovery and the incident was reported to the Judicial Police. Officers from the Homicide Brigade examined the cell, while Public Security Police officers also attended and photographed the scene.

RTP reported that there is no video surveillance inside the cells, although cameras monitor the corridors.

The death is being investigated separately from the drug-trafficking case.

Three foreign nationals arrested

João Oliveira, head of the Judicial Police’s National Unit for Combating Drug Trafficking, said the three people arrested were Indian, Italian and Colombian nationals.

The Indian national was a crew member of the container ship. The Judicial Police said he was detained on strong suspicion of being involved in the alleged trafficking operation.

The Italian and Colombian nationals were found aboard the vessel in an irregular and undocumented immigration situation. They remained in custody and appeared before a court on Wednesday.

According to Portuguese media reports, the Indian crew member was believed to be the only one of the three detainees who could provide significant information about the suspected drug-trafficking network.

Five tonnes of cocaine seized

The five-tonne seizure was one of the largest cocaine seizures ever recorded in Portugal.

The operation was led by the Judicial Police’s National Unit for Combating Drug Trafficking. It was carried out with the Portuguese Navy and Air Force, Britain’s National Crime Agency, Spain’s National Police and the Maritime Analysis and Operations Centre for Narcotics (MAOC-N).

Authorities intercepted the ship while it was sailing in the Atlantic, about 640 nautical miles off Portugal. The vessel was boarded under difficult conditions.

The Portuguese Navy then escorted the ship to Sines, where it arrived in the early hours of Tuesday, Aug. 4. The cocaine was removed from the vessel.

The ship was identified as the Maersk Nokwanda, a Hong Kong-flagged container ship serving ports connected to the banana trade in Ecuador and Colombia’s Pacific coast.

During its latest voyage, the vessel called at Posorja and Machala in Ecuador, Buenaventura in Colombia, and Balboa and Colon in Panama. It then crossed the Atlantic, with its planned route taking it towards Tangier Med and other Mediterranean ports.

Portuguese forces boarded the vessel with the help of helicopters. They found two stowaways aboard and arrested them.

Investigators also seized equipment allegedly used to navigate, transport and throw the cocaine into the sea.

The container ship left Sines on Wednesday morning and headed for Morocco.

Drugs allegedly meant for transfer at sea

Portuguese investigators suspect the cocaine was supposed to be transferred from the container ship to other vessels at sea.

The drugs would then have been taken towards landing points on the Portuguese or Spanish coast.

The Judicial Police said it had dismantled a criminal group suspected of bringing large quantities of drugs into Europe using a container ship.

The five-tonne seizure brought the amount of cocaine confiscated in Portugal this year to about 28 tonnes, according to authorities. That figure has already exceeded the total amount seized in the country during all of 2025.

The seizure came shortly after Portugal’s Maritime Police found and seized two tonnes of abandoned cocaine near the Troia Peninsula.

International cooperation

Operation Skydrop involved Portuguese, British and Spanish authorities, as well as MAOC-N.

The Judicial Police said investigators also seized objects connected with navigating, transporting and throwing the cocaine into the sea.

The investigation into the suspected drug-trafficking network is continuing. Authorities are examining the roles of the people arrested and how the cocaine was supposed to be transferred from the container ship to other vessels.

A separate investigation is examining the death of the Indian crew member in custody. The two other detainees remain in custody after appearing before a Portuguese court.
